Hi there!
As tomorrow is the exam and we haven't had class since last Friday, I HIGHLY recommend you do certain exercises to get ready for the test!
Click here to practice doing several activities about Simple Past: it's very easy, just click on the left side and you choose which item you want to work with. Don't forget the exercises about There was/were!
Plus, remember to revise the vocabulary from pages 13 (ex. 5), 14 (ex. 1), 15 (ex. 8), and 16 (ex. 2); you can put this into practice by doing the review on page 21.
Good luck and see you tomorrow!
