solutions, anyone?

so I’m a junior and I took the SAT in March and I’ve been planning to take it again in June. I also want to take at least 2 SAT subject tests (probably lit and us history) and was thinking of taking them in May, but I realized I’ll be out of town. I know for lit it doesn’t really matter when I take it, but I wanted to take the us history one close to the ap test/finals so I can remember everything. But I can’t take both the SAT and subject tests in June. I don’t want to postpone the SAT or the subject test until after summer because I’m afraid I’ll forget all the info, and I’ll be on a community service trip in Nicaragua all summer.
Thoughts?
thanks

I would postpone the SAT until after the summer if you have to, because there isn’t as much info to remember for it. You can still do some review after you get back from your trip.

Agree. You really should take the subject tests(s) when the material is fresh. In contrast, with the SAT you really don’t need to do much over the summer but just take a few practice tests and maybe study some vocab. The October test is accepted by schools for ED.
