Hello Nakul,

you secured 69% in the HSC board its good .but the admission procedure to the IIT college will be through the JEE examination only there will be no other alternative way to the IIT admission and also the minimun required to the IIT colleges is the 75% in the secondary board exams so if you have 75% iin the secondary board exams you secure a seat in IIT

yes definitely if yoy score good in jee advance then you can get a seat at the IITs and many more colleges like IISC.But there is criteria for board result.You need to score more than 65% or you must be in top 20 percetile of you board result to secure a set at the IITs.Best of luck for your result and futire education.

Hope it helps.Thank you.
