<p>If you look in the general catalog & Math Dept website it states: "Credit option: Students will receive no credit for 1A after taking 16B and 2 units after taking 16A."</p>
<p>There's no mention about restrictions on units if you take 1a after 1b.</p>
<p>The undergrad advisor said that you still get units but not Grade points so it doesn't affect gpa. A friend of mine asked the math department but hasn't got an answer yet.</p>
<p>If i remember its on the 9th floor of evans. The math department office is there and if you ask for the math advisor they should point you to one of the advisors room.</p>
<p>I think when u exit the elevator, go right, then left, and look at the doors some of them shuld say math advisor.</p>
