<p>I going to chimed in here about Math 11 series and Math 22 since I took it. Math 11 is fairly easy sailed through it no problem. Despite it being water-downed calculus, I found that I was prepared for Math 22 in fact I found it much easier then Math 11B since it was just the same thing as the 11 series but with an extra variable. Math 23 I can’t comment on since I never had to take it.</p>
