<p>And is there a "max" amount of units you can take?</p>
<p>No (unless you take classes in the summer) and no.</p>
<p>well, yes, there is a unit cap per semester that would require permission from the college to go above. College of Letters and Sciences students are normally held to no more than 20.5 units per semester [Courseload</a> Regulations - Office Of The Registrar](<a href=“http://registrar.berkeley.edu/current_students/registration_enrollment/courseloadregs.html]Courseload”>http://registrar.berkeley.edu/current_students/registration_enrollment/courseloadregs.html)</p>
<p>To go above those maximums would require approval from your college. It is not that difficult to get permission, as long as you are doing very well in classes at the normal loads, but it is not guaranteed.</p>
<p>Would going above the unit cap cost extra money?</p>
<p>it would not cost any more (except for books and lab fees or small incidential things like that which may be associated with a particular class regardless of total units)</p>
<p>Okay, thank you! :)</p>
