10 tips & tricks crack exam success
10 Tips & Tricks Exam Success :
1. Motivate yourself!
What are you goals? Remember why you are doing this. Write
down what you want to achieve and think about how it would
feel to achieve this.
2.Manage your time well
Make a plan. Write it out. When will you study, for how long?
Stick to your plan and make sure you have ‘spare/extra study’
sessions to cope with the unexpected.
3.Choose your study time/place well.
Know yourself, when and where can you concentrate best?
Avoid distractions.
4.Break it down.
Divide your study topic into ‘chunks’ or sub-topics. Decide
how many to tackle in each study session. Try and study by
topic not time.
5.Study effectively.
Choose your topic. Write your topic heading first. Scan the
topic material you need to learn and write down the sub-
headings or sub-topics. Now quickly read the material but
don’t take notes. Check your sub-headings; are they right
or do you need to add/remove some? Now, re-read and take
notes using your preferred method. Try a mind map!
6.Test your knowledge.
Work through some past paper questions. Which areas need
improvement? How is your time? Do you know how long you
need to answer a question?
7.Know how and when to unwind.
Make sure you take plenty of short breaks during study.
20 minutes is often considered to be the upper limit for
unbroken concentration. But make sure you don’t break for
too long. Do an energiser exercise during study to refresh
your concentration and take the occasional longer break for
snacks and meals. Most classes do not last longer than 90
minutes for a reason! Know what works to allow you relax.
8.Get regular sleep.
It is important that you try and get some sleep not just the
night before your exam but also that you are generally well-
rested. Most people will sleep better if they try and keep to a
fairly regular schedule.
9.Prepare the night before.
Get ready for the exam the night before by sorting out your
clothes, any materials you need and making sure you know
where essential items such as your keys, wallet and mobile
phone are.
10.Leave yourself enough time on the day.
Make sure you leave in plenty of time for the exam so you
are not rushing. It can be helpful to try and clear your mind
before the exam (many people find listening to music or the
radio good for this). In the exam, try not to get stuck on
difficult questions. Glance over the whole exam. Know how
many questions there are and how much time you have.
If you get stuck on a particular question, move onto the next
question; and return to the difficult one later.

Subtopics under each chapter in physics for IIT-JEE
Subtopics under each chapter in physics for IIT-JEE
Now a days JEE aspirants consider physics as one of their favorite subjects because it not only helps them to develop critical thinking but also helps them to acquire problem-solving skills. It also happens to be a key subject particularly in competitive examinations like JEE Main and Advanced. In JEE exams, the questions asked in the physics section are generally based on the conceptual knowledge about the topic. For scoring well, you are required to have a strong conceptual base along with the practical application of concepts.
There are around 20 chapters included in JEE Physics syllabus and out of these, there are several important topics that must be focused on while preparing for JEE Physics:
Some Important Chapters Physics:
1. Mechanics: The questions asked from this unit are either directly based on some mechanical concepts or might require considerable skills in mechanics, which could help you in solving the question. JEE mechanics is all about few fundamental laws like – Newton’s laws of motion, laws of gravitation, laws of conservation of linear and angular momentum. All these laws form a framework in physics and thus it is expected that you should understand all these laws and apply them to practical problems.
Questions from mechanics could be solved easily by the combination of Laws of conservation of energy, Newton’s laws, Equation of continuity, Work energy theorem, Laws of conservation of momentum and Bernoulli’s theorem. These topics have applications in other chapters of Physics too. Therefore, they are probably the most important topics that you need to focus on.
2. Electricity and magnetism: Due to its vastness and the level of difficulty, this unit is very crucial for both JEE Main and Advanced. Every year lots of questions are asked in JEE from this unit. You don’t have to worry much about physics in JEE if you practice and prepare well for this unit. You can expect lots of questions from capacitance, coulombs law, and its applications.
Don’t get scared of complicated circuit problems and try to understand the fundamentals for reducing complicated electrical circuits into simpler ones. Practice several questions from Kirchhoff’s laws and series-parallel circuit reduction and also don’t ignore the theoretical aspects of the topic. Memorise all the formulas and practice several questions from electrostatics, Motional EMF, and magnetostatics.
3. Fluid mechanics and Thermal physics: Familiarize yourself with the calculations of work, heat, Carnot engine and its efficiency, internal energy and the laws of thermodynamics. Several times in JEE Exams questions from the laws of thermodynamics were mixed with the calorimetry. Practice several numbers of questions from fluid mechanics as well.
4. Oscillation and waves: Every year around 4 to 5 questions are generally asked from this unit. Try to understand certain complex topics like the principle of superposition, reflection & refraction of waves, forced and damped oscillations, resonance, Simple Harmonic Motion, Doppler effects in sound through visualization. It will not only make you understand the concepts easily but will also help you in retaining it for a longer period of time.
5. Optics: This is one of the easiest and high scoring unit. Practice several numbers of questions from this unit and try to focus more on certain important topics like Interference, Young’s double slit experiment, wavefront, Huygens’ principle, Laws of reflection & refraction, Polarisation, Dispersion of light by the prism, Lens Formula and Magnification.
6. Modern physics: Mostly theoretical questions are asked from this unit. Focus more on understanding the Bohr’s model of atomic structure. Formula-based questions are generally asked from this unit, therefore, memorize all the formulas properly and use them correctly while answering the questions.
IIT JEE Physics Important Topics
JEE Main 2019 Physics Section
The physics section was deemed to be the toughest section among the three sections. The questions were tricky, lengthy and students had to make an extra effort to solve the questions with their logical and reasoning skills. The physics section consisted of a total of 30 marks.
In this, 13 questions were set from electromagnetism, 8 from mechanics 2 from modern physics, 3 from optics, 3 from thermodynamics, 1 from SHM and Waves. In this paper, 10 questions were quite easy, 17 were moderate and 3 questions were difficult.
