1) I put my phone on silence mode when i sleep because i do not want to get/receive any sort of interruption.

I put my phone on silent mode when I go to sleep because I don't want to be interrupted.

2) If you don't study, you will not be able to catch up with the class/lesson thought in class.

I'm not sure what you mean by this. You would only need to "catch up" with a class if you weren't there (for example, because you were sick and missed the class). Perhaps you mean:
"If you don't study, you won't be able to keep up with the class (or the classes)".

3) Did you break 20 plates in one incidents/occasion or in several occasion/incidents.

Did you break 20 plates all at the same time, or at different times?!

4) I have started my revision for [STRIKE]all the[/STRIKE] the/my final exams or i have started revising for final exams.

As marked above, "my revision" and "revising" are both OK, but I would say "the final exams" or "my final exams".

Please see my notes above.
