The 19-year-old says though she comes from a filmy background she doesn't want any help from her family.
"Every now and then he (Mahesh) tells me where he feels the need but I like to be on my own and I want to learn from my mistakes," said Alia.
The movie sees her play the role of Shanaya Singhania, who comes from a very affluent and a rich background.
"Shanaya loves her clothes, bags, shoes and she is very brand conscious. She also comes from a dysfunctional family and feels lonely and is looking for that one person who can love her unconditionally," Alia said.
"Student Of The Year" also stars newcomers Siddharth Malhotra and Varun Dhawan and it is releasing on October 19.
Alia says she is excited and nervous about becoming an actress at a very young age.
"I am just 19, I finished school and just walked into movies. So I am really scared and nervous as to how it will turn out to be. I didn't plan this, it just came along and I am enjoying every bit of it."
