Affordable BS to MS Computer Science path

[SpicyMe23]

Would you then suggest I continue working on certifications and taking courses through courera, edx, etc. without worrying about a second bachelor's or master's in CS? I already have a BS in biology with a fair bit of math work (through Calc III and DiffEQ, but I never took linear algebra or discrete).

If certifications and continued education through those (mostly free) means would be sufficient for getting an entry level job for now perhaps that is what I should focus on.

I was worried that if I cannot get a MS in Computer Science that it would prohibit my ability to grow career-wise later in life.
