how much time do i need????

i need to take a french and math II SAT subject test. how much time do i need??
ps.i need to take it on the same day. my math is ok and my french needs work (like a lot) and i really need to ace them. pls advise…

@DEEPUSS You already asked this question. The answer depends on your math and French proficiency (how good is “ok?”).

Also, is there a reason why you’re taking Math II and French if you need to spend a lot of effort preparing? Is it possible to take a different subject test in an area you are better at?
