I'm beginning my toeic course today.
I'm very confused for that what class should I joint to?

Actually, I get high score in testing, and the staff of cram school
suggests me to join the 750 score class, but I'm afraid I couldn't
keep up with foreign teacher.

After the first class, I'm thinking about transform to the 750
score class.

Maybe I'll be regretting to change the class, but if I won't try
I'll never know what the edge of my english level.

Is it too adventure?..HAHAHA..I really don't have ideas of that.

So, pls give me some advise, tks.
