Hey Anima,

Hope you are doing well!

Since,You have 1 year time,you need to use it very wisely,Here,are the  steps you should follow while prepartaion:

1)MAKE A PLAN:

"Failing to Plan is planning to fail"

Therefore,dear make a plan and always try to complete the syallabus atleast a month early soo that you can ddevote maximum time for Revison.

2)TIME MANAGEMENT:

"Time once lost can't be brought back"

So,dear make a proper time table of what to complete and when to.

Also,assign a time daily for revision of all that you have studied.

3)SELECT THE RIGHT BOOKS:

4)MOCK TEST/TEST SERIES:

After you have completed the course its very important to test the topics in which you need to give more attention,and the best possible way to do it is by giving more and more tests,Hence,choosing a good test series or a good sample paper book is very important.

5)REVISION:

"Repetition is the mother of Excellence"

Once you have identified  your weak areas,then Practising and revising each and every topic is extremely important.As,you give test series identify your weak areas and keep revising on it.

Make a note of all the important things you need to memorise and memorise them daily.
