SAT

Hi Alok,
You don't have to retake your 11th to take the SAT. Instead work extra hard for your 12th and simultaneously prepare for SAT. You can also give the SAT after your 12th. Many students take a year gap and prepare for SAT, at the same time involve yourself in extracurricular activities too.
