<p>I started with Math31B as a freshman too, I had only taken the Calc AB test, got a 5, my junior year of high school so I did some light reviewing over the summer. I took Math 31B with Radko, she was ok, some of my friends said that her accent was a little hard to get used to, but my high school had a russian teacher so her accent wasn’t too bad. Math 31B starts out with integrals so its fairly easy in the beginning before the First midterm… then it starts being things that weren’t in the AB test. You can google some practice midterms some teachers from ucla left online to see what your up against and [UCLA</a> Department of Mathematics](<a href=“http://www.math.ucla.edu/ugrad/courses/math31ab/31Boutline.shtml]UCLA”>http://www.math.ucla.edu/ugrad/courses/math31ab/31Boutline.shtml) gives you the syllabus of what you’ll be learning. All in all, its alright to start in Math 31B, warning though I think alot of engineers start off there too?</p>
