How many elective courses can a doctoral student take?

<p>Thanks for the advice. I’ll keep that in mind when it comes time to apply for grad schools, and I’m looking for a lab/adviser. I’ll definitely be focusing more in self-study and thesis research, but I still want to take a course or two per semester for the first couple years to broaden my horizons a little more. </p>

<p>I’m looking at Berkeleys graduate program, and in the course requirements section, it mentions that the minimum requirement for graduate students is 12 units each semester. Are these 12 units pertaining more to thesis research/self study, or does this imply courses too?</p>

<p>If I’m seeing things right, the individual study for doctoral students can take up a maximum of 8 units per semester. So, I guess I’d have 4 units left to fill up anyway. They recommend taking a couple of the special topic seminars to fill the other units, but I imagine I’d be able to substitute a course in instead.</p>
