Past years' questions

This morning I received an sms asking about past year questions. The conversation is as follows:

-Bonjour madame. Can you give me old questions for French?
-You can consult the past years' questions at the resource centre.
-Merci madame. I afraid I get badder marks than my test.
-The comparative for bad is not badder.
-Nak buat apa compare madame?
-Ok. Example: the comparative for big is bigger.
-Oh. Jadi better la ye madame?
-No.

...a few minutes later I received the last sms...

"Takkan bagger kot madame?"
