Should I take science prereqs over the summer?

I go to a top 20 undergrad (according to US News) and science classes here are naturally really hard. So I was planning on taking Physics, anatomy, and calculus over the summer online at a different college (less known, not prestigious). However, I am worried that dental schools will think I am avoiding taking these classes at my current undergrad. The majority of my dental school prereqs will still be taken at my current undergrad. Do you guys think I should do it? any advice is appreciated.
