2 Complete the sentences with words from Ex 1.

2 The teacher gets angry when people cheat in exams.

3 Olga is really good at English. She always gets good marks in English tests.

4 We've got exams next week, so I'm revising all weekend.

5 I hope the teacher likes my project when I hand it in this morning.

6 We're all really tired today so it's difficult to concentrate on our work.

7 I always pass maths exams, but some students in our class sometimes fail them.

8 I tried to copy my friend's work, but the teacher saw me.

3 Read four student posts on an online forum. Then match the problems (A-E) to the people. There is one problem you don't need.

This person ...

A - thought someone copied their work. Ellie

B - failed a test. ← There is one problem you don't need.

C - didn't hand in homework. Anya

D - can't concentrate on their work. Leo

E - got a bad mark. Melissa

Ellie → Try to talk to your friend when you see her.

Melissa → Ask your teacher for some advice to improve your skills so you can get a better mark next time.

2 C - I often (spędzam czas z) hang out with my friends in town at the weekend.

3 C - Anuska isn't really ill today - she (wagaruje) is skiving off because she doesn't like exams.
