.Hii

As you mentioned your jee main percentile is 81.14...with this percentile ..there are  less  chances to get Govind Ballabh University ..

As per previous year cut-off to get admission in  GB Pan university, candidate's jee rank should lie between.12000-110000..and with you jee percentile you rank will be between 160000-180000....but you may go for counselling (every round)...

Or you may also try for other colleges:-

• Graphic era university
• Graphic era hill university
• DIT university
• Dehradun institute of technology
• Uttaranchal institute of technology
• School of engineering
  

Hope it will help!!
