FCCPT Evaluation

Greetings everyone!
I am getting close to sending my documents to the FCCPT so they can evaluate. I have taken a course in Physics and a course in Chemistry, each one semester long. On the CWT-5 it mentions that one course of each of those classes is required, but also that a whole year of chemistry and a whole year of physics is "preferred".
I have this spring semester to take another physics and chemistry class, but I don´t know if it is worth taking them, or simply study for the NPTE.. what advice can you give me? Are those "extra" chemistry and physics classes worth it? will they make a difference in the evaluation?

Please help! Thanks!
