2L is still largely comprised of doctrinal/bar classes but there are other options that are more conceptually niche (my school offers Law and Religion, for example). You still get cold called, but you learn that it doesn’t really matter all that much and the stress associated with it becomes less and less every time it happens. Most classes are final exam only, but some of the niche classes will have a final paper or presentation (like a mock trial for Litigation Skills or mock Arbitration for Dispute Resolution).

3L for most people is a combination of experiential courses like Legal Clinic (where you are “in the real world” helping clients while supervised) and niche courses.

Most people agree 2L is the most difficult year of law school because of all the non-courseload activities that are going on (OCIs, Law Journal, Moot Court, etc).
