Failing pre boards (PCM)

Yep pre board 1 is ending tomorrow. I have no hope for math I just might fail. I am definitely failing physics and maybe even chem. The other 2 subjects (CS and Eng) are fine, I can manage that easily. But PCM is absolutely f*cked for me.

Now I have a little over 50 days left for Physics. What should I do because I've never gotten more than 28/70. On top of that I have to focus on Math and Chem too because during mid-terms I got 40 in Math and 37.5 in Chem.

I also went ahead and made the mistake of getting a girlfriend. I have however warned her that I might cut everyone off and she may not know if I'm even alive till 11th March.

But that's whatever.

My aim is however high I can possibly get. So if there's a way I could get full on all subjects I might just do it. But the problem is I have no idea how.

Please advise.
