It's good that you are very passionate about your course ,but you still have time for that,so be enthusiasted.
Regarding course selection in PUC it doesn't matter ,you can choose whatever you want but I would say take electronics.

Hi Sauvik,
It's hard to compare, both TPR and Manhattan are quite popular. One way to find out is by visiting the centers and find out the statistics. Try to get in touch with ex and current students. Compare the study materials and the schedule, most importantly are the instructors certified? Diagnostic tests are important, enquire how realistic are the mock tests with the actual tests. Finally it's upto an individual how he deals with competitive tests no matter what. So choose the center as per your suitability.
Hope this helped. Please feel free to revert for any clarification.
