Pretty easy, overall.
At UCI, if you're planning to take the physics 7 series, you either need to pass an online test or take physics 2. You can go either way as you can take the online test once per quarter, so you are able to pass later on if you initially failed, or you can take physics 2. Physics 2 is a good place to start physics as it is challenging and is actually part of the Physics 7C course. Physics 2 covers the first two chapters of a physics textbook while Physics 7C covers the same 2 chapters but an additional 8 or so chapters in the same amount of time, if I'm not mistaken.
The highlights of the course would be vectors, derivatives, and the kinematic equations. The kinematic equations are by far the biggest part of Physics 2. It is the main topic from the beginning to the end of the course. As long as you memorize the 4 kinematic equations and learn how to utilize them, you should be fine.

Advice for students:
Take this class if you have little to no experience in physics but need to take physics. Monday is a lesson, Wednesday is group work where each group of 6 has to solve around 5 problems and can leave once they are done, and Friday is the quiz. The class is 2 hours long each day. The quizzes are fairly easy as even if you don't understand, they will make sure that you have the right answers. During the quiz, you can have them somewhat help you and correct the questions as many times as you need until you get it right or until the time runs out. There are no midterms and the final is fairly easy. The online homework is far more difficult than the actual quizzes so if you can learn how to do those, the quizzes should be a breeze.
