AITA for ignoring him?

So, I recently had my exams and a day before my maths exam, a guy from my maths tution asked me to send pictures of all the papers that we have worked. Now, the problem is that we have worked a shit ton of papers since the beginning of the year.

So i told him that he can look at the marking schemes online and ask me for help for the difficult questions. But then he kept asking me to help him just this once. I started getting annoyed at this point because he was the one who skipped tuition all year round and I'm the one who always sent him all the notes that he missed which he did not even bother copying. Besides, the marking schemes are so detailed that even an idiot can understand them. It literally won't even take him a minute to just type the paper in the search engine and he would get all the youtube videos and websites that explain the questions step by step.

I politely told him i can't because i also have to revise. But he was still persistent. So i ignored his messages and went back to studying. I still haven't opened his chat since that day. So AITA for ignoring him?
