If you placed into Fundamentals of College Mathematics, there is very little that your professor will assume that you already know, besides maybe the multiplication tables. The course starts at the very beginning, with addition and subtraction of signed (positive/negative) numbers, and fractions.
HOWEVER, it will move VERY QUICKLY! It could be called All of Grade School Math and All of Middle School Math, and Two Years of High School Math in Fourteen Weeks. It is ESSENTIAL that you attend every class, work all of the problem sets that are assigned, and go for help at the Academic Success Center (call 215-951-2799) AS SOON AS you get to problems that you find challenging.
