@fashionista99 - my daughter did biomedical engineering and some of the classes for the major from her college were approved as biology for Texas. Essentially, you can go to the second link and try out your college to see what they consider valid for Biology that you can take at your school. You can also submit a request to TMDSAS asking for some classes you took at your school to be classified as biology based on content. If you interview and do get in, you can get the schools also to accept an equivalent class or request waiver if TMDSAS does not accept the request.
The first link tells you the requirements for texas medical schools and also special requireements that may be needed at specific schools. several of the schools in texas require CASPer.
