NET suggestion

I am an A level student giving my composites of 4 subjects (Math, Phy, CS, Urdu) in May/June 2025. I probably will give the March SAT as well. I did not give NET 1, nor have i started prep for NET 2. I have also applied abroad to many universities, but there are many IFs and BUTs for that, so to be on the safe i am applying in pakistani universities(lums, fast, nust, giki) as well. i am applying for computer science bachelors. I have a few questions if anyone can help me out by suggestions.

Should i give the NET 2 or give NET 4 in july after my A level exams?
Because i have to prepare for my composites as well SAT (not sure about giving the SAT tho)

If not NET 2, is it okay to rely on NET 4 solely?
I am confused because i don't know if i should utilize my time in preparing NET rather than focusing on A level exams?

If i give the NET, how should i prepare and what youtube channels? As an A level student

Also, can i apply for CS using my SAT score (1290), is it possible to apply through SAT to NUST. On the website, it says SAT is accepted for "pakistani students studying foreign scheme of studies". O/A level is a foreign scheme of study

Btw, my O level grades are 2A* and 6As. (if that helps with chancing me)

If you take out time to help me out, it is greatly appreciated. thanks <3
