I have an English exam on February 3rd for English. I have an English exam on February 3rd.

It's more common to put the subject before "exam".

If I get a high enough score, I canwill move up to the next level (course that can teach me) where I will be taught translation and interpretation skills. If I get a high enough score, I will move up to the next level (course) where I will be taught translation and interpretation skills.

I think using "will" makes this sentence sound better. I also wouldn't say "next level course", I would say "next level" or "next course". "Enough" just implies that there is a threshold score

If I get a high score, I can move up to the next level course that can teach mescore sufficiently, I can progress to learning translation and interpretation skills. If I score sufficiently, I can progress to learning translation and interpretation skills.

This is how I would write more concisely

However, the pass rate ins 10% in general. However, the pass rate is 10% in general.

However, the pass rate ins 10% in general. However, the pass rate is 10%.

this would be more concise

However, the pass rate in 10% in generals around 10%. However, the pass rate is around 10%.

Instead of saying "in general" you can say "around." "about 10%" is also okay.

I will makedo my best efforts during the next 2 weeks. I will do my best for the next 2 weeks.

"Do my best" sounds better
