From what I can tell, there are not many classes offered online through A&M. My son can only do night time classes or online in summer and he looked for some through A&M and couldn’t find any. He’s taking at our local CC to satisfy the remainder of ICD and UCC requirements not fulfilled by his major or AP.
Take the math 2412, that is the common course number for Math 150 at your local CC. I would not take the equivalent of Chem 107 at your local CC, because the GPA won’t transfer and he must take two of the sciences at A&M and it is highly recommended to take Physics 208 elsewhere.
