Help needed

Hey!

I took both SAT math 2 and spanish with listening in november, getting 550 and 750 respectively. I know my math score is low, and that’s where I’d need your help. In december, I’m supposed to take the SAT with essay, but I’m thinking of re taking the math 2 exam instead.

But here comes the problem, then I’ll have to take the ACT to make up for the SAT with essay. The thing is, ACT december registration is only available as standby testing, so no seat or test booklet guaranteed. Basically, if I choose to re take the SAT math 2, I might end up with no SAT/ACT score to send to colleges.

Does anyone if standby testing would be a good idea? (considering the fact that I’m testing in Europe, not in the US)
