Hello Ganesh,
You need to apply for a single window counseling program under Anna University called TNEA. If you belong to TN or if you are a TN native student, then you can apply under regular admission. Otherwise, if you are an other state student, then you need to apply under other state admissions. The admission is based on your board exam scores.

Hello Sathish,
Though the cut off gets reduced, the competition level will be high. So, it is better to have a cut off of 195 and above to get aeronautical engineering at MIT Chennai, if you belong to OC. For other categories, the cut off varies.

Hello Rishi,
Your cut off is too good to get you a seat for B.Tech Food Technology at Anna University ACT campus. Try your best at the counseling. The JEE main scores are not taken into account for admission. All the best.

You can definitely apply for Anna University and in affiliated universities.
You have to first visit Anna University and buy a counselling form.
