There wasn't much grade inflation in my major, then again I saw tons of unhappy premeds. I didn't know it but my college bio sci branch was the favored premed major, had I know that I'd pick a different school. Despite this, the average in most of my classes was a C and the valedictorian had a 3.8. No idea about humanities, it seemed at the upper undergraduate level it wasn't cake, or at least it wasn't in ethnic studies.
At my community college grades were super inflated in most intro courses. My first calc class was an exception since only 7/30 passed and the professor refused to address the grades.
I barely cleared a 3.0 in the last 2 yrs of college. That and my limited lab experience (spent most of those 2 years internship hunting) makes me feel extremely nervous about my upcoming application to graduate school. I feel like the adcoms will LOL at my application (and stupidity) and insta-toss it in the trash. I graduated in <4 years so I wonder if that will help me.
