What is considered a solid/safe GPA for the top programs in the country for chemistry?
It depends on what you consider “top” (personally, I can’t define that) and what field you are interested in. If you do a bit of homework and tell us (a) what your area of interest is, (b) what your GPA is, © what your GRE scores are, (d) what your research experience is, and (e) what schools you are interested in after having looked into them with regards to the area of chemistry you seek, then we can probably give you some suggestions. Nothing is certain ins highly selective graduate programs, of course.
