Hello Aspirant,

As tancet is the entrance exam conducted for getting seat for good college for MBA/Mtech/M.E  and you got 79 percentile of marks  so you may or may not get seat in the good colleges or universities but chances are very less to get seat in good colleges or universities to calculate your rank use it the below formula  and calculate your rank

40 + (10/S) ( R– M )

By this we can calculate our rank and tancet results are declared by Anna university and you wanted get seat in chennai there are very good colleges but we cannotexpect government colleges  based on your percentile so let's hope for the best study well and work hard to get good marks in the future examinations ALL THE BEST for your future and i think my suggestions and knowledge may be helpful to u.
