Are my Accuplacer scores decent?

I recently took the Next Generation Accuplacer tests for math and English (and got admitted to the college!), and I was wondering if anyone knew what the approximate SAT score equivalency was (because I haven’t taken the SAT yet) or knew of whether or not the scores are considered good. I’m a sophomore, and I took these tests for Running Start admission (dual enrollment program), but I didn’t get to study as much as I would have liked to, so here goes:

Math: 275

English (not Writeplacer): 300

Thanks!

Accuplacer tests are intended to help you determine which English and math courses you should take based on what you previously learned and remembered, so there is no SAT or ACT equivalency.

Here is an example college’s placement guideline for (next generation) Accuplacer scores:
