HOW TO PREPARE FOR JEE MAINS IN HOME EFFECTIVELY

Here are some tips given by your senior yaswanth to prepare for JEE mains effectively in home it self
  1. At first you should know all things about the examination.
  2. You should pay attention in class
  3. You should develop speed and accuracy
  4. You should be honest with your work
  5. Self analysis must be there
  6. You should believe in yourself and you should be confident with your studies
JEE Main Preparation
1. KNOW ALL THINGS ABOUT EXAM
             This exam is conducted all over   India who are going to join engineering.
This is conducted by NTA .
                  This exam is conducted twice a year in January and April.
       PATTERN:
                      The question paper contains 90 multiple choice questions in which 30 are from maths 30 are from physics and 30 are from chemistry.
        In my view you should concentrate more on chemistry which is more scoring
 subject
        And then you can concentrate on maths and then physics which the calculations given are lengthy
           SYLLABUS:

2 .PAY ATTENTION IN THE CLASS
                       Most topics in JEE main syllabus are from NCERT books .you should be regular in the class and should be honest.
You should through with all concepts and all all formulae.
FOR:
       MATHS:.  Formulae should be in finger tips .
         PHYSICS:. All concepts should be clear .
All derivations should be known perfectly.
      CHEMISTRY: Should follow NCERT books carefully. Sometimes direct questions would be asked in JEE mains.

3. DEVELOP SPEED AND ACCURACY
             To solve more questions in JEE you should develop speed and accuracy by doing more practice daily. Doing aptitude problems daily.

4. HONEST SELF ANALYSIS
                  Doing  problems in Khan academy , Meritnation , byju s websites.
                          Solving online mock tests in computer daily and analysis where you are.
and be honest with that .

5. CONFIDENCE ON JEE
               You should be confident on jee and you should think that I can fulfill jee examination.
                 Finally, you should think always positively and to maintain positive attitude.
You should think "I can do it".

 
      
JEE Main

  
BEFORE ONE MONTH PREPARATION:
           you should practice "previous year JEE main question papers". This will help you how the paper would be and you get clarity on that thing .
