Main thing is that which college you are targeting on Gujcet..

If you are free to go in any college then You don't need any particular score But if you are targeging Top 2-3 colleges then definataly you have to be in top 500..

For LD engineering Your merit rank should be in 1-300 for Open category..It will vary from field to field..But if you Are in top 500 then u ll definately get one of the fields in LD.

To be in top 500 you need to score more then 100 from 120..

For vishwakarma the merit will be Mostly same as LD..because people who didn't get LD they re moatly opted for vishwakarma Engineering college..so from where LD engineering stop their admission the second choice of candidate is vishwakarma..so You must have to score 90+ to get in to that Top 2 clges..

With lesser marks you get the downgraded clges(Self financed)
