Hello Vishal,
I see that you too are a victim of the myth about private colleges. If you have the skill set a company wants and you have a good percentage (at least 70) with no backlogs, you can end up at a respectful position in a reputed company. To the company, skills matter not the college.
While B.Tech in private engineering college is more expensive compared to B.Sc., it provides you in-depth knowledge and if you're able to grasp it, you end up in a much better job than what B.Sc can provide. On the other hand, due to in-depth knowledge, some students find it a bit difficult to pursue B.Tech and go for B.Sc.
So, it's upon you to decide about the level of hard work you can put, the fees you can afford and the outcome you want. This should help you to find out whether to go for B.Tech or B.Sc.
