Students who have enrolled in the calculus sequence Math 135-136 or Math 135-138 sometimes switch to a major which requires Math 251, the third term of calculus. In particular, biology majors who have taken Math 135-138 sometimes change major to biochemistry, which requires Math 251. These students should switch to the Math 151-152 track as soon as possible.
Math 135 to 152
For someone who has already taken Math 135, the transition to Math 152 is not too difficult. However one should check with the Head Advisor when planning such a switch. Here is a study guide, which is out of date as the syllabus for 135 is presently closer to the 151 syllabus, making the transition easier. On the other hand as the syllabus for 135/6 and for 151/2 may change slightly as we change textbooks, it is always best to consult the Head Advisor (or our course material pages) in such cases.
Math 136 or 138 to 251
The transition from Math 136 or Math 138 to Math 251 is quite difficult. Math 136 or Math 138 cannot be substituted for Math 152 as a prerequisite for Math 251. Students wishing to take Math 251 after having taken 136 or 138 should take Math 152 for E credit.
Occasionally students who took 136 learn the missing material (mainly infinite series) on their own and take a proficiency exam for 152. Here is a study guide for that transition. This is not available to students who have taken Math 138 as that course is targeted exclusively to biology majors and covers very different material from Math 152.
