Will it actually matter?

Hi
I am planning on taking the subject tests either in october or november. I plan on majoring in math or computer science so I’m planning on taking Math II but I’m not sure which other science subject to take. Biology is out of the question. I feel like chem might be the easier of the two but while I do well in chemistry I don’t really like it, on the other hand the physics one seems harder yet I like physics a bit more. Does it make a difference which one I take?
Also I know that if I take them in November and want to take the french subject test it will be with listening which I know will be the easiest part since I do better in listening comprehension, but with my luck the cd player will die during the exam.
Will schools actually care about the language test for those majors or should I just save my money?

Unless if the college(s) require you to take a specific Sat II test for a specific program (like Northwestern’s HPME program requires you to take Chem + Math II), then you should focus on what you actually like. Language Sat II’s, from what I was told by my aunt’s friend’s daughter, is only used if you want to opt out of a language course during college (like in Columbia or Yale). Since you want to major something in the mathematics field, I think that the language Sat II would be overlooked.
