<p>You may want to preview them on the web site to get an idea of how difficult they may be for you. However, since CS 70 and EE 42 are not lab, programming, or project courses, their workload should be relatively light compared to CS 61A or other CS courses with programming. A non-lab non-programming non-project course will likely be comparable to a math course in workload, although CS 70 and upper division CS theory and math courses will involve more proofs and derivations than typical calculus and linear algebra courses at the freshman and sophomore level.</p>
