Malala Yousafzai, 20-year-old Pakistani activist and world's youngest Nobel Peace Prize laureate, began her studies at the University of Oxford this week.

Yousafzai, whose advocacy for girls' education provoked a bullet to the head from the Taliban, is continuing her own schooling at one of the world's leading universities.

"5 years ago, I was shot in an attempt to stop me from speaking out for girls' education," Yousafzai tweeted Monday. "Today, I attend my first lectures at Oxford."

After her formal acceptance to Lady Margaret Hall in August, Yousafzai said she will study philosophy, politics and economics.

Yousafzai, who addressed the U.N. on her sixteenth birthday and met privately with Queen Elizabeth and Barack Obama, still faced freshman jitters. Tweeting last month, Malala asked her more than 987,000 followers:

"Packing for university, any tips? Advice? Dos and dont's?" adding the hashtag #HelpMalalaPack.
