NET PREP HELP!!!!

I have started preparing for NET- 4 (the registration will probably close around june 20, so i have until start of July to prepare i hope), i am currently enrolled in another uni (made a stupid mistake last year and started preparing for NET 4 only 15-17 days prior to the test) so i needed suggestions of how i can manage net prep and uni together (only option of dropping out of that uni is if i secure marks in NET)

Also, what channels are the best? Sir hashim zia for maths but what about for physics? sir bilal zia's videos are exremely long and i got recommended physics for seconds but they are teaching only mdcat (would it help for NET?)

do tell me the best way to prepare? also i am planning to give two different NET ( one Net engineering (SEECS) and the other for design (SADA)
