Math 135, 5-credit Version
In this version there are 4 meetings per week, the two lectures, a workshop session, and a practicum. Generally the section number is in the range 70-79 for such courses, and the practicum is listed separately as Math 131. So if you sign up for 135 Sec. 72, for example, you will be registered automatically for 131 Sec. 72 at the same time, which is the 1-credit practicum that goes along with it.
According to our own studies students who take this course do better on the average. Of course, since more time and effort is involved, this is not surprising.
