Some tips for preparation

1. When you start preparing for any exam, your first and foremost step should be to go through the syllabus of that exam along with the questions asked in the previous years of that exam and

A. Try to understand the trend

B. Try to understand the level of questions

C. Identify your strong and weak topics and plan how much importance to give to each topic accordingly

D. Work on the precise approach to solve questions so that maximum number of questions can be solved in the given time

2. Complete your preparation in stages according to the nature of the exam:

While preparing for some exams in which basic questions are asked in large numbers, prepare for them by completing all the chapters in the first stage.

A. Understand the basic definitions and formulas

B. Understand which formula to use in which situation through an example

C. Remember well what each notation in the formula means

D. Understand the process of how the unit and dimension of quantities are determined

E. Write down the formulas with three parameters in a separate diary

F. Memorize some standard solved questions.

Dear Students

Please note the following tips:

To approach a question either write the formula of desired quantity and then put the values

directly or indirectly from given values in question

write the main equation of that *topic* so that you can know which quantities can be deduced

from the *given* values and *main equation* 

Fo example in questions of photo electric effect you can always *start* the question by writing

*main equation* and then putting given values and checking what you can find by putting

those values. 

Main equation in above case the Einstein's equation of photo electric effect.

The photo electric effect equation of k.e max can be written in various form.... 

Like if frequency is given then in terms of frequency. 

If wavelength is given then in terms of wavelength. 

If cut off wavelength is given then *work function* can by replaced by *hc upon lambda not*

If cut off frequency is given then work function can be replaced by *h nue not*

Attempt the motion related and force related questions. By drawing diagram. 

Hint- to cross a pole a train need to travel a distance equal to its length... Because pole is said

to be crossed only when the guard's wagon crosses the pole.

You all are encouraged to attempt as many questions as possible based on topics taught in

class, Unsolved one can be discussed in class with teacher.

Practice well.. Always try to compare questions with those *done in class* so that solution can

be obtained. 

Test is meant to judge your understanding and analytical ability and to make you all aware

about where to take cautions and where to use common sense. 

So feel light while attempting it.

Better understanding of concepts through numerical solving is required. 

प्रश्न भले ही नया लगे, उसे हल करने का प्रयास जरूर करें तब ही कान्सेप्ट क्लिअर होगा और कैपेसिटी बढेगी

Physics to math, hidden to math, chapter formula likhkar aage badhen

Jaisa class me aapke teacher karvayen. Waise hi har question ko approach karen

Jo concepts samajh na aa rahe hon... Unhe baar baar likhkar dekhen.

Tip-

Question naya lagne par, turant use , class me padhe huye frame me change karne ka try

karen...

Monoatomic gas has only 3 translational dof. Diatomic rigid gas molecule has 3 translational dof

+ 2 rotational dof = 5 dof. Diatomic non-rigid molecule has 3 translational + 2 rotational + 1

vibrational dof = 6 dof. Polyatomic linear molecules have 3 trans + 2 rot + f number of

vibrational = (5+f) dof

Practice each questions 2-3 times until you become used to Or comfortable with the process... 

I don't fear the man who practiced 1000 punch. 

I fear the man who practiced one punch 1000 *times* - Bruce Lee

It has been noticed that some students lack in problem solving just because they don't attempt the questions on their own.

All are advised to atleast attempt the questions twice as per method taught in class..

It is just like putting value from question to formula.

To understand which formula is to be employed just remember the standard type of questions asked for each formula you learn.

Do it topic by topic and chapter by chapter.

" Repeat the example taught by your teacher atleast 2-3 times untill you become comfortable and confident with that method only then attempt new questions. "
