Let's take a quick flashback trip to a few years ago, when Teen Mom 2's Jenelle Evans was in rehab for heroin addiction. Bet you didn't think she'd be able to turn her life around, but girlfriend beat all the odds and she's currently 100 percent sober!

What's more, she made the bold decision to go back to school to get er medical assistant degree, and she just closed out the semester with straight-A's. Yep, girlfriend has morphed into a genius.

"Next week is my last week of school and STILL pulling through with straight A's. #GoMe," Jenelle tweeted on June 19, adding, "School done!"

So um, somewhere between her first and second tweet she finished school? Not quite sure, but either way we're super proud of Jenelle. Don't forget that this girl completed her semester while heavily pregnant with her second child, and managed to pull herself out of bed every morning for class. What a champ!

And for those of you wondering whether Jenelle will go back to school once she pops out her baby, the answer is absolutely yes. Though this southern belle might take a few online classes so she can stay home with her baby, she has every intention of finishing up her degree, and setting a good example for her children.

Are you surprised that Jenelle's doing so well in school? Let us know below, y'all!
