<p>I’m fairly certain you have to take a minimum of 13 units per semester over at Cal. Besides that, I believe your assumption is correct: As long as you stay below the unit ceiling, you can keep enrolling for however long you would like. 61 + (13x5) = 126</p>
<p>Looks like you MAY be able to pull it off (the issue is that it might not be so easy to keep your workload at exactly 13 every semester). Just make sure you stay below 130 by the end of the 5th semester. If you hit that number, you wont be able to enroll for the 6th</p>
