JEE PREPARATION TIPS

- By Kailash Sharma

Practice makes perfect

After studying a chapter, make sure to attempt
questions on the topic. It will give you a better
grasp of the concept. While solving questions, if
you get stuck, do not look for solutions directly.
Try solving it yourself, make mistakes and then
correct them. Problem-solving skills and the
correct approach to cracking questions for
clearing exams are not going to come to you
magically. It's a slow and steady process. Keep
trying until you crack the question yourself.
Getting answers to questions is something
which is expected in exams, so make it a habit.

Mock tests and PYQs are the key

Make sure to attempt partial mock tests after
completion of a topic and full-length mock
tests after syllabus completion. PYQs are the
best study material for JEE. Analyse your weak
points and work on them. Keep getting a little
bit better every day. These small steps will make
a big difference. If you have solved previous
20 years papers of JEE Advanced, then you
have completed 90% of the work required for
getting into Ills.

Be organised

Study a chapter and keep your core concepts
clear. While studying, make sure to make notes
and write down important formulas. This will
not only be useful while revising, but will also
help you remember them better. Don't rely only
on PDFs. Write down all the important points
and include proper illustrations in your notes.
Date them and keep a track of which topic

can be found where. Consolidate all past year
JEE questions subjectwise and chapter-wise.

JEE Mains vs Advanced-The dilemma

Most students think of preparing for JEE
mains first, then after clearing it, moving on to
preparing for JEE Advanced. But the truth is,
the preparation for these go hand in hand. If
you have prepared for JEE Advanced properly,
then you are well prepared for JEE mains, and
even for your Board Exams. The syllabus for both
exams is the same. It is the complexity of the
questions and the core conceptual clarity that
makes them a little bit different, which can be
mastered with consistent practice.

Segregate The Syllabus

Divide your syllabus into monthly and weekly
segments and assign yourself practical targets to
achieve. Spend more time on your improvement
areas, while not being over confident and
ignoring the topics you're good at. Maintain a
balance. Selfevaluate regularly.
