Je ne comprends

Je ne comprends - I dont understand, that was my state of mind in the class today. Day 1 when i learnt about 14 words/sentences i thought its gonna be easy, but today when things got more intense with more than 60 sentences/words/numericals coming my way i realised this is not going to be so simple and easy. I am hoping for things to get better from here and I use less of google translator after my 100 hours language course.
