No you can't do that. You gave GATE exam this year then you can use that mark to get an admission in this year only. You can't use this year marks or rank to get an admission for coming year. This is strictly prohibited by the board. This will be unfair for other candidates as the pattern and level of difficulty and number of candidates appearing changes every year.
This is simple concept that the mark of current is to be used in the very same year only. It can't be used in the next year or coming years.
Hope it helps!
