hi arijit ,

to be able to get a decent engineering college also , it is better to be having a good or atleast an average rank in the enterance examinations .

but if you wish you take admission through your board percentage , 62% might not help you get a seat in some decenet colleges . you can get it it some average colleges , but for a better future it is always advicable to join in a good college .

you can , go through the management quota for admission .

all the best
