hello aspirant,

The cutoff is not released by the authorities and it will be released on the official website.Cutoff changes every year due to many factors like total students appearing for exam,difficulty level of paper,category etc factors,so its quite tough to say exactly the cutoffs.as you did not mention your category considering you from GEN category, 78.6 percentile would fetch score around 25 based on previous year analysis , and your score , you can have chances in the following colleges :

kingston engineering college

ponjesly college of engineering

hindusthan college of engineering and technology

sri ramakrishna institute of technology

sns college of technology

Er.perumal manimekalai college of engineering

nehru institute of management studies

sns college of engineering

sona college of technology

note that these are based on previous year cutoffs,as cutoff varies each year so are your chances into colleges.for more information refer to: https://bschool.careers360.com/articles/tancet-mba-cutoff

hope this helps,

thankyou.
