Hey 1st-year-here,
You are in a tough position, but my mom always said: "Persevere and do the best you can do or let them kick you out of the course, don't ever give up". School is rather black or white.. You are already enrolled in it, you have already put some time and energy.. My sister was studying arabic and she was about to give up, her classmates had prior arabic knowledge and she had great difficulty until the end, but with my mom's advice, she persevered and ended up passing her course! It is really up to you and only you know what's best. If you put aside the fact that your grades depend on the last test then maybe just maybe you will even get a better grade than your 94 goal! Good luck buddy
