How you classify courses on your AMCAS application is important. All courses that you classify as Biology, Chemistry, Physics and Math will count toward your BCPM GPA. AMCAS will provide your BCPM GPA (as well as your non-BCPM GPA, total undergraduate GPA, and graduate GPA if relevant) to medical schools.
Computer engineering and computer science have a lot of overlapping characteristics, but the major difference is found in how the obtained skills are used. While computer engineering focuses more on hardware and electronics, computer science focuses on computer programming and software design. Both areas involve the study of advanced mathematics, physics and programming, but computer engineers are more likely to use those skills to build hardware than to build programs.
Computer science. Computer science deals with the theoretical foundations of information and computation, together with practical techniques for the implementation and application of these foundations. Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers.
