My GPA at the beginning of junior year was a 3.84. Now, after junior year, it's a 3.69.
I feel like shit. I felt so great about having a 3.8 (which is considered high) but now it's all gone to waste. The whole year behind me only hurt me. I might as well have not taken it.
Mine tanked a bit over time too. The thing is that early on, you are mostly taking gen eds and/or stereotypically easy courses. And also for me, I had less on my plate with not having a job. The courses you take in your final two years are often the most difficult and thus your GPA is going to suffer a bit for it. I'm not really sure how people manage to have upward trends in GPA as opposed to downward. I guess if you are a super genius or if you didn't try your freshman year, you'd have this trend...but I'd wager that most people's GPA tends to decrease throughout college.
