What school are you trying to attend? Check the requirements and prerequisites.. I know in California they only allow one repeat for science classes.. Good
depending on how good you are with pre algebra its doable BUT math is really demanding and so is a&p. ..check and see if your school offers math workshops. good
A&P with another science? I wouldn't do it. General Anatomy is VERY demanding, like 5 hours studying everyday and your taking the A&P with 1 or 2 other classes .. its doable but you'll never...
