UC Berkeley students are required to complete their Reading and Composition (R&C) classes before entering their junior year in order to be better prepared for the academic rigor demanded of upper division classes.
Read more about the R&C requirement for students in the College of Letters & Science, for students in the College of Engineering, and for students in the College of Chemistry.
If you haven't satisfied this requirement you still have the opportunity to sign up for the classes during Berkeley Summer Sessions.
