18 credits too much?

I’m taking 18 credits in a term and I’m not working

Comm 111 Public Speaking 3 credits
PE 231 Lifetime Health and Fitness 3 credits
WR 227 Technical Writing 3 credits
BA 211 Principles of Accounting 4 credits
MTH 111 College Algebra 5 credits
Is this too stressful or no?

First term? Don’t do it. Later, maybe.

That does not look particularly demanding. If you can do the work, it’s fine.

Looks good to me. No work and no sports to add on? Should be fine.
