big problem

dude
since you have cleared your pe2, it is obvious you have the potential to clear ca final also.
it is not as tough as people apprehend
on the last days
concentrate on theory more
especially the ones that you have studied before
since our memeory tend to be short.
and ensure that you are in the hall for the entire 3 hours
bye for now

p.s all the best

You Should have to allot time only in revising the subjects and not to start anything which is new for you.

Start your day with the subject which you enjoy to study and then go for the difficult subjects.

Be free because you only have to give exam, the result is not in your hand. You also know that sometimes the hardworking students do not able to clear and the limited study oriented students get through. Hence Do not worry. ALL THE BEST.

Since you should have already covered all the subjects, what you require is only a minor revision.  All that you have already studyed will be embedded in your brain, and once you see the question at the examination hall, the relevant answer will come to your mind and you will have a graphic picture of the relevant pages you have studied appearing in an imaginary screen in front of you.  Hence don't panic.

Stop reading the subject on the previous day of the examination itself and give your brain adequate rest on the day of the examination.  After finishing the examination do not analyse your answers and forget about the same. If you start analysing the answers you have written, your concentration on the next subject will be affected.  The analysis of the answers can wait till the last examination is over.
