So I’m going to be taking the French subject test this Saturday (along with literature), but I will also be taking the French with Listening test in November to see which one I do better on. I was just wondering if I should only submit my better French score, or if I should send both. Also, if I send both, does that count as three subject tests (for schools like Georgetown)? I was going to take math level II to be sure, but even though I’ve just taken the IB Math SL exam I struggle with the stuff on that test and don’t really have time to review at this point. Had I known I would struggle so much I would’ve started studying earlier 
At this point I’m just hoping Georgetown will be able to look over my only having two subject tests. But anyway, would it just be redundant to send both scores?
No. The school will consider French with or without listening as one subject. The same for Math1 and Math2. Check that some schools may require the FL subject tests with listening. If you do not use score choice, all scores will be sent anyway. The schools will look for what they want in the score report. Alternatively, you can specific which score to be sent. Note that both SAT1 and SAT2 scores can appear on the same report.
