What does this mean?

Question

I am searching for colleges with an equestrian studies course. What do the letters (A,B,C) after the course listing mean?

* Agricultural Business B
* Agricultural Economics B
* Animal Sciences B
* Equestrian/Equine Studies C
* Food Science B
* Greenhouse Management B
* Horticulture Science B,C
* Horticulture, Ornamental B,C
* Landscaping B,C
* Plant Sciences B
* Plant/Nursery Operations B
* Soil Science and Agronomy B
* Turf Management B

If it is a series, then do I have to take Equine studies A before I take Equine studies B...Because this college does not offer A or C

Answer 1

Did you find this on CollegeBoard? If so, the legend at the top says:

A = Associate degree
B = Bachelor's degree
C = Certificate or diploma

Answer 2

Classes can come in a series. Agriculture A would be taken before Agriculture B, before C. It's just the sequential sections of the course.
