I have a question concerning Pre-Reqs and PTCAS. I was looking around on the PTCAS website and know that different programs will accept different courses as pre-reqs. I have done fairly well in all my pre-reqs, thus far. However, I received a B in a gen. biology lab my freshman year ( A in lecture) and I took Zoology with lab, and got an A in both lab and lecture. Could the Zoology be used in place of that gen. biology class? Does PTCAS allow you to select the courses you want to be applicable for that pre-req requirement? Also, I can begin the application process next July/Aug for schools, can I start recording observation hours and such on PTCAS? I thought I read somewhere that they erase data entered when the new application cycle begins, or something of that nature.
