問一句英文翻譯，請各位大大幫忙！(中翻英)

I want to stop a session class, because my class is so heavy that I can't control.

I want to drop the oral course because I can't handle the workload of all courses I'm taking now.

If take 002 for your answer, you English teacher would probably agree that you don't even need to take his class, hahaha...

Notes:-(1)drop an English oral conversation class;
-----------(2)beyond my control;

---I want to drop an English oral conversation class because my courses are so heavy that it is beyond my control !

I want to stop to repair conversation class because my class is too heavy , I can not grasp.
這樣ㄇ?!

「我想停修會話課，因為我的課太重了，我沒辦法掌握。」

Notes:
1. drop (vt) a class = 停休某一個課程
2. bit more than I can chew = 因為太多...而無法應付(自找的)

I bit more than I can chew and am thinking about dropping the English Conversation class.

For the priest, then I should have said:

I've got more than I prayed for and I need to drop my knees to...

「我想停修會話課，因為我的課太重了，我沒辦法掌握。」

"I want to stop to repair conversation class because my class is too heavy, I can not grasp."
