hello aspirant,

I would like to tell you the best ways that you can do to prepare or revise for the exam when the exam is very near.

I would suggest you to only go through all the notes that you have made while preparing for the exam.

only go through self made notes , because the language/mindset in which you have made those notes are very important and you will be benifitted the most from those notes only.

make sure that you do not attempt to try for any new topic or try to make concepts clear from any untouched topics  , that will only increase the pressure on you.

some chapters and subtopics that you can visit are-
