UP Manila, Mapua or Asia Pacific?

I'm really confused so here's the deal. I passed the UPCAT with a course of Computer Science in UP Manila. But my mom and relatives say that ComSci is hard especially in UP. Information Technology is my target course, by the way. So I plan to take entrance exams in Mapua and Asia Pacific College. This time, my dad says that it's also hard in Mapua and it is also quarterm. No idea about APC yet. So what do you think? Answers, suggestions and comments are very much appreciated. ^^
