Dear Vivek
Don't loose hope as 5 month is enough time to crack JEE with good rank. You need to speedup your study but don't miss conceptual part. Start PCM simultaneously. Don't waste your time in confusion just start doing the things and devote as much time as you can in studies.and give emphasis on the revision. revision is very important. I have seen many students who have cracked JEE with this much time preparation. Just be consistent with your studies. From now onwards manage your time properly and dont waste it. and one important thing give more emphasis on Quality rather Quantity i.e do one book for each subject but understand the concepts properly and give time for revision. as far as test series is concerned, it doesnt matter to much. your main aim is to score good in JEE. Scoring good in test series doesnt guarantee good rank in JEE.
All the best.
