No , it won't be any trouble infact it's really common u will find many people dropping one year after 12th to get admission in desired college and course there is nothing wrong in investing one year in ur future .

No, absolutely not. Now it has become a common trend to drop one year. Also now marks will not be deducted afterwards as it was used to happen earlier.

So go for it. Drop one year and study hard.

Good luck.

I hope u get ur answer
