I've appeared for HSC exam this year ( 2014 ) from Maharashtra board and got 72%. By few marks I didn't clear the JEE mains exam too. So i decided to take a drop. Even though I'll be coming in top 20% percentile next year, I still want to go for the supplementary exam for boards which will be held in October to increase my marks. Which means the memo will bear 2015 as my passing year and not 2014. Will this affect my admissions to NITs or IITs next year? And is the decision of repeating 12th good or not with respect to doing masters abroad? Please let me know ASAP.
