Opinions about UCR academics are all over the spectrum, specifically in regards to the instructors. Most students believe the actual classes are up to par with UC standards, as UCR even offers courses not available at any other university. Talking to peers is the best way to find out “inside” information about the best and worst professors and courses. Large classes are becoming increasingly more common due to budget cuts, so the smaller discussion sections are a godsend for struggling students.
While many students find the majority of professors to be immensely knowledgeable, some find interaction with them to be difficult, since they're often very busy. TAs generally are more approachable and accessible, as they are in charge of the mandatory discussion sections of large classes, which allow for more one-on-one possibilities. The professors and TAs both have required office hours, and it can only benefit the student who takes the time to utilize the opportunity to clarify lectures and assignments or simply for a chat. Due to class variety and quantity being trimmed because of budget concerns, keeping a full schedule of required courses can be reduced to sheer luck. It's highly recommended to stay proactive and consistently exchange information with fellow students about the classes available.
