Pop star Britney Spears is planning to go back to school for her kids.

The 33-year-old singer has confessed that she finds her sons' homework so hard that she has decided to go back to school. In a candid confession, the "Piece Of Me" hit maker revealed that she is brushing up her skills in pre-algebra in order to understand her sons' homework.

"Some of it is hard for me," Fox411 quoted the star. "Next year when [Preston's] in fifth grade, he's going to be doing pre-algebra, and I'm taking classes so I know how to do it!"

The star appears to be quite involved in her sons' lives and reportedly keeps a check in terms of toys and cash they get. Moreover, the singer has a unique point system in her house that  encourage her sons, Preston, 9, and Jayden, 8, to perform well in school in order to get a toy of their choice.

Spears, who rose to fame as a teenager with her debut album "Baby One More Time," was enrolled in Parklane in Mississippi when she got her big break and made her the youngest female artist to have sold a million records nationwide in history.

The singer is dating producer Charlie Ebersol and admitted in the interview that she might get married again. The singer fuelled engagement rumours last weekend when she was spotted sporting a huge diamond sparkler on her finger.

Spears' next single, named "Pretty Girls," is a collaboration with the Australian rapper Iggy Azalea, Daily Mail reported. Its music video will be released on May 5, following the "The Britney: Piece of Me" concerts at Planet Hollywood in Las Vegas starting on Apr. 15.
