4.0 at UCLA?

<p>I am transferring to UCLA this fall as a junior and a history major. I held a 4.0 at smc and was wondering how hard it is to maintain a 4.0 gpa at ucla. I won't be working and I feel like I stay on top of my academics, but I have heard that it is pretty hard to get a 4.0. has anyone been able to do it and what kind of tips would you give?</p>
