Career Technical Education courses on FLVS?

Im a competition programmer (on my schools team) going into 10th grade. There are lots of Career Tech courses like ones on OOP Java and another data bases, I was wondering if any one has taken any of these classes and what they thought of the difficulty of them. I want to take a bunch to ‘saturate’ (if you will) my transcript with these type classes as I want to be a CS major. If you have not taken them possibly you know someone? there is not much (any) information on these courses anywhere so trying to find out the difficulty and time needed is nearly impossible. (if you have taken one and want to know my level of experience with CS I know Java, currently learning Obj-C and have participated in and won multiple programming competitions throughout the country).

EDIT: I also saw the Introduction to Information Technology (intro to IT), anyone taken that class as well as any of the other career tech education classes?
