Hi, 

As i understand your query related to this. 

But, all government colleges has very high merits for admission and also in todays the competition in engineering also increases. 

As you had said you had 68.20% you would get admission chance in government colleges In last rounds of counselling if seat availability is there in government colleges. 

Otherwise you can go in GEC government colleges like bharuch and godhara, etc where the merit rank or merit list are less. 

Or you can go in colleges as vadodara institutes of. Engineering where fees are least and education is very good with practical knowledge. 

Let me know if you still have any query in comments
