Last year the order of topics in Math 8 and 13 were changed, so that it is no longer possible to get credit for Math 8 via any exam other than the math department's placement exam. It is also possible for a very advanced student to get credit for Math 13 by passing a special exam, arranged through the math department's advisor to first year students. During Orientation Week, all the academic departments at Dartmouth will have open houses where you can meet faculty and discuss majors and courses. In addition, there will be special meetings for students interested in honors courses, advanced placement, etc. Read your Orientation Week schedule carefully to identify these meetings, and be sure to attend the ones which pertain to you.
Labs are one afternoon per week.
They also take a first-year seminar, or Humanities 1 and 2 instead of the seminar. IMPS will not conflict with English 5 or Humanities 1-2. If you want to take IMPS, you should be careful not sign up for a first-year seminar that meets during the 9 or 10 hours. Some foreign language and introductory biology courses conflict with IMPS, requiring you to postpone them until the spring term. The mathematics covered by IMPS is basically that in Math 8 and 13, with some material from Math 23.
