How much are summer courses?

I'm lookimg to get slightly ahead in pre-med reqs as a freshman non-STEM major. I was planning on taking Bio 311D, SDS 320, Ch 302, and Ch 104N. (Heavy on the chemistry classes because of the new ochem requirements) I planned on doing this because I thought each class was 500 💀. But then, I realized it's only for specific courses. How can I find out the price of individual courses/total summer tuition? (I am a Texas resident)
