@Ispitfacts girl try getting help from your female friends , tell them your problem and ask them to go between you and that senior . Try to avoid him physically , even don't answer whatever he's asking - changing subject that doesn't relate him . This may sounds bad behave but it's called setting boundaries . You don't need to be assumed of setting your own boundary.
Change sits if you notice he's trying to sit next to you , I bet next thing he gonna do is insulting in front of everyone to get attention . Insult back in funny ways . Be brave and have confidence.
