I am hinting nothing of the kind. Here are a few samples of schools that do not permit substitution. I will add there are many schools that noted in detail that Biochem could substitute for Ochem II but do not mention any other substitutions from their lists. That would imply it is the only course they regularly allow substitution for.

Can other science courses like Organic Chemistry II or Microbiology be used to complete your prerequisites?
No. We will not accept any other science courses as substitutions for our required prerequisites.

Q: I took Organic I and Organic II. You have a Biochemistry requirement. Can’t I substitute Organic II for the Biochemistry?
A: There are no substitutes for the prerequisite courses. You can apply, receive a secondary application, interview and even be accepted without taking Biochemistry. However, you will not matriculate without the course.

Substitutions are not acceptable for any of the required courses, and the science course work should be taken in a seated class.

1 academic year of general chemistry, general biology, general physics, and organic chemistry--all with laboratory (biochemistry can be substituted for part of the organic requirement) Please note: Advanced Placement credits are acceptable to fulfill requirements, however, we recommend applicants to complete additional science courses to maintain their science knowledge.
