Which university did Lady Gaga attend before dropping out to pursue her music career?

Stefani Joanne Angelina Germanotta (born March 28, 1986), known professionally as Lady Gaga, is an American singer, songwriter, and actress. A popular contemporary recording artist, she is known for experimenting with new musical ideas and images and for her unconventionality and provocative work.

Gaga began to play the piano at the age of four, wrote her first piano ballad at 13, and began playing at open mic nights a year later. At her high school, she played the lead roles of Adelaide in "Guys and Dolls" and Philia in "A Funny Thing Happened on the Way to the Forum". She also studied method acting at the Lee Strasberg Theatre and Film Institute for ten years. In 2003, at age 17, Gaga gained early admission to Collaborative Arts Project 21 (CAP21)—a music school at New York University's (NYU) Tisch School of the Arts—and lived in a NYU dorm. At NYU, she studied music and improved her songwriting skills by writing essays on art, religion, social issues, and politics. During her second semester of her sophomore year in 2005, she withdrew to focus on her music career.

Gaga has sold an estimated 27 million albums and 146 million singles worldwide as of January 2016, making her one of the best-selling music artists. Some of her singles are among the best-selling worldwide. She has also been noted as a touring force, having grossed more than $300 million in revenue from 3.2 million tickets for her first three worldwide concert tours.
