how to study less and get higher grades
By Gohar Khan
Summary
## Key takeaways - **Focus on effectiveness, not hours studied**: Don't get fixated on the amount of time you spend studying. Instead, focus on how you study, like quizzing yourself or teaching others, rather than just rereading or highlighting. [01:00], [01:35] - **Read backwards for efficient cramming**: To study a chapter quickly, start with the summary and key points at the end, then skim headings and key terms, and finally read the first and last paragraphs of each section. [01:40], [02:38] - **Batch similar tasks to avoid context switching**: Group similar tasks together, like math and science problems, or essay writing, to minimize the mental transition cost and save time. [02:47], [03:51] - **Use constraints to boost productivity**: Apply Parkinson's Law by giving yourself less time than you think you need for a task, like setting a timer for 10-20% less than the estimated completion time. [04:41], [05:44] - **Don't get stuck on one problem**: Avoid wasting time on a single difficult problem due to the sunk cost fallacy. Instead, move on to other problems and return to the challenging ones later. [07:32], [08:23] - **Tag notes for targeted review**: During lectures or while reviewing notes, mark topics you're unfamiliar with using symbols like stars to focus your study time on areas that need the most attention. [10:10], [10:47]

there are two kinds of students in the
world here we have student a who has
been studying for 6 hours is on their
third coffee cup and has been
highlighting their notes rereading the
textbook and doing flashcards all night
long and here we have student B student
B has a very calm 2hour study session
they know exactly what to review how to
review it and barely waste any time
highlighting their notes or rereading
the textbook come exam day I think you
know who gets the better grade if you
couldn't tell it's me by the way wait
how I studied four times longer than you
in this video I'm going to teach you how
to study less and get higher grades so I
graduated as the valid dictorian of my
high school and I went on to double
major at MIT and I'm not saying that to
flex instead I want to provide some
context so back in high school I took 11
AP classes peing at five my junior year
and then at MIT I decided to double
major pretty late which required me to
stack up on a bunch of classes all at
once so as you can imagine I had to be
very efficient with my studying and the
entire time I had to keep my GR grades
up so my first tip is to disconnect
yourself from the number of hours that
you study as a student it's very easy to
get fixated on the amount of time you
spend studying instead of how you
actually study and I get it right
because it's very hard to measure the
effectiveness of a study session but
something like the amount of time you
spend is a very concrete measure though
it usually masks the true nature of the
study session for example let's say I
study for 5 hours now did I spend those
5 hours rereading my notes and
highlighting everything I possibly could
or did I quiz myself pretend to teach
others and Tackle my weakest Concepts
first those two behaviors would yield
drastically different results all right
so now that you're in the right mindset
let's move on to tip number two read
backwards this sounds really weird I
know but bear with me this is a very
valuable tip especially if you're
cramming for an exam at the last minute
so the night before an exam you're
probably tempted to pull out your
textbook and read the chapter the test
is on but there's a problem the chapter
is probably very long and you don't have
enough time so what you're instead going
to do to start at the end of the chapter
you're going to start by looking at the
chapter summaries and the key points and
then work your way to the beginning and
now that you're back at the start you're
still not going to read the chapter
normally you're going to do what I like
to call a first pass you're going to
look at all the headings all the charts
all the bulit terms all the colorful
boxes to get a high level understanding
of what the chapter is about but of
course you're still missing some of the
key details so now you're going to do a
second pass and no you're still not
going to read the chapter normally
instead you're going to go Section by
section and read the first paragraph
skim the body paragraphs and read the
last paragraph So now after the second
pass you should have a decent
understanding of what the chapter is
about but if you still have time to
study now you can go back and read every
single word individually all right and
with that let's move on to tip number
three batch your tasks so a huge problem
that a lot of students deal with and
maybe even you is something called
context switching so for example the
mindset that you have while reading
something is different from the mindset
you have while writing something which
is different from the mindset you have
while solving math problems switching
from one form of thinking to another
takes time something I like to call the
transition cost for example let's say
you spend an hour answering some brutal
calculus problems and then you have to
write an essay for your English class
both of those tasks require very
different forms of thinking it's
probably going to take you a good 10 to
15 minutes just to get into the groove
of the essay writing process so to save
time while studying you have to minimize
the number of transitions through a
technique called batching and the
premise of batching is very simple
you're going to group together similar
tasks and Tackle them together so for
example instead of doing some math
problems then an English essay then some
science problems and then a history
essay you're instead first going to do
the math and science problems first
together and then you're going to do the
two essays this way you only have one
mental transition instead of three now I
use batching all the time in fact I'm
using it right now once I finish filming
this video I'm going to go ahead and
film another one because I already have
the light set up I have the camera set
up I have the background set up if I
were to film these videos at separate
times I would just waste time taking
everything down and then putting it back
up oh and I have another quick tip for
batching tasks once you batch your tasks
you might notice that within a batch
different tasks have different degrees
of difficulty I always recommend that
you tackle the easiest task first within
any given batch this way it's much
easier for you to transition into that
new mental state that you might need to
be in so for example if you bash
together a bunch of writing tasks like
write an essay work on a presentation
and write a discussion post you should
probably do the discussion post first
because that'll take the least amount of
effort and then you can follow this up
with the outline and then the essay tip
number four is to give yourself
constraints now one of the easiest ways
to spend less time studying is to give
yourself less time to study and no I'm
not being factious I'm 100% serious so
there's an old adage called Parkinson's
law that goes as follows work expands so
as to fill the time available for its
completion now this idea sounds fancy
but it's simple however much time you
give yourself to do a task is however
much time you're going to take for
example if you give yourself 3 days to
work on an essay you're going to take up
the full 3 days but if you give yourself
only 3 hours you might be surprised to
see how fast you can actually finish
that essay so now while it's nice to
space out your deadlines you don't want
to give yourself too much time to work
on an assignment because then you're
just going to have the mental comfort of
telling yourself oh I have hours or days
or even weeks to complete this task and
then you'll just work at a slower Pace
now the easiest way to take advantage of
Parkinson's law is to set a timer before
you start an assignment first ask
yourself how long is this assignment
going to take then reduce that number by
10 to 20% and set your timer accordingly
again you might be surprised by how fast
you can actually finish that work so
this technique is something that my apsy
teacher actually used at the start of
the school year he only gave us 30
minutes for each exam towards the middle
of the school year he only gave us 25
minutes and then towards the end of the
school year he only gave us 20 minutes
minutes now Believe It or Not by the end
of the school year most students were
able to finish the exams even when only
given 20 minutes I remember at the start
of the school year he told us he was
going to do this and we all thought that
it was nuts but turns out he was on to
something DeMarco if you're watching
this shout out to you you helped me
learn how to take test effectively all
right and my next tip is to leverage AI
now one of my favorite ways to cut down
on study time is to use AI tools like
grammarly who's the sponsor of this
video so many of you know grammarly as a
spelling and grammar tool but do you
know that does way more than that let's
say you have to write an essay you're
staring at the prompt but have no idea
what to write about this is where
grammarly can help just open up
grammarly and ask it to help you to
brainstorm topics then tell grammarly
what your essay is about and almost
instantly it'll give you a handful of
topic ideas oh and it doesn't stop there
once you have your topic grammarly can
also help you draft a research plan and
even give you an outline now once you
have the outline you start writing your
essay and along the way grammarly
ensures that your writing is clear and
concise it'll check for common mistakes
like passive voice subject verb
disagreement and misplaced modifiers but
it'll also analyze your piece as a whole
and provide suggestions for cohesion
flow and tone in fact with grammarly Pro
you can indicate the exact tone you'd
like to go for whether it's personable
confident empathetic engaging witty or
direct oh and once you're done writing
you can also use grammarly's plagiarism
detector to ensure that you can submit
your essays with confidence grammarly is
a must have for all students sign up and
upgrade to grammarly Pro for 20% off
using my link and now now back to the
video so tip number six is don't idle
and this again comes from an AP psych
teacher so while you're working through
an exam or doing some homework problems
you are inevitably going to come across
some problems that stump you and I'm not
talking about problems that are just a
little bit challenging I'm talking about
problems that you legitimately do not
know how to answer no matter how hard
you try now the best thing that you can
do in this scenario is to swallow your
ego and move on and this was a huge
issue for me back in school if I had
spent 20 or 30 minutes trying to solve a
problem I would feel terrible if I moved
on without figuring out the answer but
this ties into a psychological
phenomenon known as the sunk cost
fallacy now if you're not familiar with
the sunos fallacy it is the phenomenon
whereby a person is reluctant to abandon
a strategy or course of action because
they have heavily invested in it even
when it's clear that abandonment would
be more beneficial in other words just
because you put a lot of time and effort
into solving a problem that's going
nowhere does not mean that you need to
waste even more time in most cases
you're better off tackling other
problems first and then coming back to
the ones that stumped you and this
requires being comfortable answering
things out of order so if you're doing a
homework assignment maybe you answer the
last problems first and the middle ones
and then make your way to the start and
if you're working through an exam the
same principle holds don't ever feel
compelled to answer all of an exam's
questions in order unless they build
upon each other just try to find a
foothold somewhere work off that and
then tackle everything else so tip
number seven is to do mindless work
first so there are two kinds of tasks
you have fixed tasks and then you have
variable tasks fixed Tas tasks are
usually mindless work like working on
flashcards or trying to find images for
a presentation variable tasks usually
require more mental energy for example
writing an essay or brainstorming ideas
for a group project now you should do
your fixed tasks first and here's why so
this bar represents the amount of time
that you have for studying if you drop
in your variable tasks first they're
going to follow Parkinson's law in other
words they're going to inflate and take
up all of your available time and now
you won't have time to fit in your fix
tasks now fixed tasks on the other hand
don't inflate like variable tasks
something like create 20 flash cards is
always going to take the same concrete
defined amount of time so by doing your
fixed tasks first you create a
constraint for your variable tasks so
when you drop them in yes they're going
to inflate again but this way you manage
to fit everything so this is a concept
that's much easier to understand
visually and shout out to my editors who
I know have done an amazing job showing
you how it works oh and by the way this
is a concept that I came up with and
have been following for years let me
know in the comments how you feel about
it and if it makes sense because I'm
down to craft more productivity rules
but I just want to make sure I don't
sound like I'm crazy up here okay and
the eighth and final tip is to tag your
notes so students waste a ton of time
rereading notes I have wasted a ton of
time rereading my notes and this is
usually because in the days leading up
to an exam we don't really know what to
focus on we just tell ourselves oh my
God there's an exam coming up for unit 3
time to read everything I have about
unit 3 but the reality is within any
given unit there are topics that we know
like the back of our hand hand and
others that we're not super familiar
with so if you want to spend less time
studying you have to spend less time on
the topics you're already comfortable
with and that's why you should tag your
notes during lecture while your teacher
is speaking if they say something you're
not too familiar with just put a star or
some other symbol next to the bullet
point this way when it comes time to
review your notes your eyes are
automatically drawn to the areas that
you need to focus on now if you forget
to tag your notes during lecture don't
worry you can also do it after class
just pull out your notes skim them as
quickly as you can and tag any points
that you're not super familiar with so
that wraps up today's video hopefully
you enjoyed it and by the way comment
below to let me know how the school year
is going for you so far are you enjoying
