Hi there!
As tomorrow is the exam, I HIGHLY recommend you do certain exercises to get ready for the test!
Here, there are several exercises to practice the affirmative, the 3rd person -s, the Do/does, There is/are (on the left you can choose which item you want to work with) and some/any.
Plus, remember to revise the vocabulary from pages 19 and 31.
Good luck and see you tomorrow!
