Try the old final exams for calculus 1 and 2 at your college to see if you really need to retake the course(s). If you know the material well, do not retake, since it will just be added time commitment for nothing. Do the same with the old final exams for physics. If you want to add a minor, it is best to take all advanced placement that you reasonably can in order to clear additional schedule space.
1 credit is assumed to be 3 hours of work per week of in-class and out-of-class time. So 19 credits are assumed to be 57 hours of work per week. A more typical 15-16 credits are assumed to be 45-48 hours of work per week. Courses with projects, labs, or art (architecture) studio tend to be higher on the workload than courses with just lecture and discussion.
As noted in reply #8, the standard schedule is:
MTH 141 (4) calculus 1
CHE 107 (3.5) chemistry 1
CHE 127 (0.5) chemistry 1 lab
EAS 199 (3) seminar
ENG 105 (4) English 1

Suggest that you consider modifying it the following way:
A. Based on how well you do on MTH 141 and 142 old final exams, choose your math course accordingly (MTH 141, 142, or 241).
B. If you need to take PHY 107 and/or PHY 108 based on the old final exams, and you are in an advanced enough math course (see the physics course prerequisites), you may want to take one of them instead of CHE 107/127, since physics is typically a more critical prerequisite to later courses (check your curriculum specifically). If you do that, be sure to take CHE 107/127 later.
C. If you have AP English language score of 4+, you can skip ENG 105 and choose some other course instead (architecture?).
