487 on COMSAE form 108i :(

Hey guys I received a 487 on my COMSAE for level 2 and my exam is in 10 days. I'm really worried as I thought I would do much better on this. My first COMSAE I took through the school was like a 450. Any advice?

My only option is to take a leave of absence if I want to study longer but obviously don't want to do that.

Please help with advice, thank you.
