Which math class: Math 21A or 21B

<p>Hi, I am wondering which math class I can enroll in for this upcoming year. I took Calculus AB and BC in high school, but didn’t take the AP test for either one. Do I have to start out with Math 21A at UCD or can I choose 21B instead? Thanks.</p>

<p><em>Edit</em>
Unrelated, but have a question about class times: I looked in the Class Schedule and Registration Guide and for each class it gives a time. I’m just confused about what this means (this is what it looks like in the time column for one class):</p>

<p>MWF
R</p>

<p>I can assume MWF means Monday, Wednesday, Friday, but what does the R mean under the M? There is also:</p>

<p>MWF
T</p>

<p>Thanks for your help</p>

<p>If you didn't take the tests you have to start with A.</p>

<p>R means that the discussion section for that class is held on Thursdays.
R= Thursday. Thus for the other example, the discussion would be held on Tuesday.</p>

<p>Oh ok I see, thanks</p>

<p>According to this site: <a href="http://www.math.ucdavis.edu/undergrad/math_placement%5B/url%5D"&gt;http://www.math.ucdavis.edu/undergrad/math_placement&lt;/a>, the math placement exam is waived for scores of 700 and above on SAT I test (I got 720). It says that a score of 50 or more on the placement test is good enough to get into 21AH (is this 21B or equivalent?), so does this mean I don't have to take the placement test to get into 21B?</p>

<p>21AH is just honors 21A, it is not the same as 21B.</p>

No, you still need to take the placement test to get into 21A.</p>

<p>I never said you didnt.</p>

<p>bend3r, was that supposed to be directed to me? I read from that website (link above) that a score of 700 or above on SAT I would be enough to waive the MPR (mathematics placement requirement). Am I understanding something wrong?</p>

<p>^ no, forget what I said.</p>

<p>getting a sore of 700 on sat i or sat ii math will waive you from MPR.(if you didn't pass, then you have to take lower classes). waiving the MPR just means you can get into math 16A or math 21A. definately take the As before the Bs. 21A is calculus for engineering wheras 16A is short calculus. there are also the 17 series which you need to take if you're in biosci but don't worry about that. have you gone to your orientation yet? all the info will be there. oh and i highly suggest taking 16 A if you didn't even take the calc AP. i passed it and i will be taking 16B. 21 series are going to be lots harder.</p>

<p>hoper I can't attend my orientation because I'm going overseas on July 23. A friend of mine who has already gone to orientation said that if you get 50+ on the MPR you are placed in 21B, but I haven't seen this anywhere so I assume he is wrong. I'm probably going to end up taking 21A because my major is engineering. :) I was just wondering if there was any way I can go to 21B since I've already taken AP calc BC in high school. But it might be better if I start out from A and work my way up again.</p>

<p>thanks</p>

<p>Aw man, I got a 690 in Math Level II. Oh well.</p>

<p>as far as I know there is no way of getting into B if you didn't take the AP exam. think of it as an easy A, i guess</p>
