Throughout this website, you will find information and activities to help you with the past tense.  
This is only intended to be a review, NOT an acceptable alternative to coming to class and learning it.
After having used this review, you should be able to correctly use the past tense with regular -er, -ir, and -re verbs, as well as some irregular verbs.  
You should also be able to recognize which verbs take être or avoir in the past.

That said, look around, have fun and learn something! :)
