REALLY NEED SUGGESTIONS FROM YOU ALL.

So keeping it short, my jee preparation is ruined-currently in class 12th, focusing only on boards. Just randomly, I saw BITSAT 2nd round dates and it is somewhere between 24 to 28th June. Now I think after boards I will be having 2.5 months almost for BITSAT and thinking to prepare for it. Though for the college fees which will be 30 lakhs, I am dependent only on education loans. Previously,I had also thought to give bitsat along with jee mains but I stepped back only because of high fees. Now,I don't have any expectation from myself that If I will be able to clear jee mains cutoff or not, that's why I am focusing only on boards so that atleast parents will not get me out of their house. And it's not easy to convince parents for the drop year, they will not agree at any cost. That is why I am thinking that atleast I will get any campus of bits. Please suggest- 1.how should I do the chapters like any youtube channel or specific teachers to follow? 2.Is phodu club is really good for bitsat preparation like their test series and books?? 3.Which test series to join and other than NCERT which books to follow?? I really need genuine suggestions and strategies from you all so that I can start from now.BTW I am general(female).
