Hello,

You got good marks in 12th dear. Now you want to take admission in this year, ofcourse you can give admission. But for 1 year gap your marks deducted some amount in admission process this is the rule. Like may be 2% or 4% it's depend on the college where you admission. And yes no problem occurs for admission because of your gap year. May be they will ask you about your gap nothing else.

All the best.
