Class search initial page is confusing (you should not have to select semester first, but assume its the most recent one), and the search option isn't as clear once you get to it as it should be.

Enroll by my requirements sounds cool and helpful but it isn't. Maybe some explanation or pointers to help but should look less intimidating and more familiar.

Next and Submit buttons are in the upper right corner most of the time which makes it harder to find and keeps it small and out of the way.

Most pages under the menu options are confusing as to what should be done next. The upperleft back button brings you back one page when one would assume it brings you up a level or to the main register classes area or home.

What purpose does the planner serve?

Too many steps between searching and enrolling or adding.

Browse seems to do the same things as search, so what's its purpose?

Asks for confirmation when enrolling and deleting but no option to undo anything (required you to manually go under whatever menu option required).

I am unable to add more classes due to taking 6 currently, but nowhere is it made clear of that. Before enrolling to adding it should say that. Even the classic version told me partway through the enrollment with a popup message. I have to manually go in and validate it myself to learn this.
