Is there still hope for me?

[spursy]

My chemistry scores for sacs have not been the best but i really want a 30-32 study score, is there any hope for me or should i give it up and concentrate on my other subjects for the exams?
To give you perspective my unit 3 average is 55% and my unit 4 average is 65% which puts me near the middle in terms of ranks
i know its bad but my cohort is very strong and the actual sacs are somewhere in the middle of mediocre and difficult closer to difficult. Do i still have a chance to get 30 or above?
