Zainab bohra mam teaches facts and asks them to mug up…unlike Rakesh sir who clears the concept from base so that any question can be attempted…
Aren’t you free to follow ur teacher and their content?
Are you really a btr subscriber? 
Or a person who reads only notes of btr without watching classes?
I wonder if you saying facts then it has to be mugged up. But if your topic does have more facts than to understand the concept you have to mug it up . Even when you think of mathematics,if you haven’t memorized formulas and theorem,your basic understanding is lost. Both co-exist. If you are preparing for entrance,its a 30-70 chance. Can’t blame. If you can’t follow you have to change your teacher
