if you cannot read it, write it, and understand the basics, your options are limited.

The most useful science course you choose depends on your academic plans!
If you're in a major that's not science, you can choose any course that you want. You can pick a class that piques your interest(s), intellectually challenges you, or that provides "an easy A" (to focus on other things).
If you 𝘢𝘳𝘦 in a science major, I suggest picking classes that meets both your General Education requirements and your Major specific requirements. You can get rid of two birds with one stone.
For all courses: Check your school's academic catalogue page to see if there's prerequisites needed before registering. Also, meet with an academic advisor to select the best course for your needs.
Enjoy finding science classes! :)
