No offense to you in particular, but I cannot figure out why people with your stats come on this forum and are honestly unsure if you have a chance at grad school! You have basically a 4.0 and your GRE scores are way above average, PLUS you have relevant experience. YES, you will get in somewhere! Its the people with 3.0s and GREs in the mid 140s who have reason to be wondering. Dont be so nervous, just apply to a bunch of places and be confident in yourself, youll get in!!
