<p>Hi. Can anyone tell me about the approximate class sizes of classes such as MA-141 & MA-241 (Calc I & II) as well as some of the Physics and Astronomy classees (PY-201 & 202 or PY-211 & 212)? Also, are those classes generally taught by professors or TA's? Are the instructors accessible and helpful? </p>
<p>Thank you for any information.</p>
