No matter where you go, you just have to study. Don't ever think that you can escape them if you are in another university. After all, isn't it what we are here for in the first place? Earn your degree and make a living out of it! I know at times it can get pretty tough. With hundreds of students in a lecture, the Professor just doesn't have time for personal attention. They can't afford it. So get a bunch of students to form a study group and it will surely help and improve your grades a lot. Aside from that, you might find some support and mentoring from them. Who know? Some of them might be your closet buddies in the future.
