Pick BSc only if you're very brilliant or will slave your way to a respectable PhD. BTech is better for high time preference, but you should know that all the common curricula like "Delhi University" and "Pune University" are spawned by satan. They will

>waste your time in irrelevant bullshit like student clubs
>make you attend almost every class
>make you slave with assignments
Your job prospects at a state uni will be a mediocre salary with a mass recruiter (aka companies that employ about 60% of the graduates). They will keep you for six months (for "training") and later kick you out, because they can only actually employ like 20% of the people they pick. The college gets a "100% job guarantee" seal, you get a job right after you graduate on your resume, and... whoops, you're unemployed.
If you're really active in extracurricular activities, suck (up to) the head of the placement organization (yes, it's separate), get good grades (8.0 and above) and never fail, and can pretend to know how to do what you're being hired for at least an hour, you'll be picked up in the second year. If you use connections and get a (technically fradulent) job before you actually know anything, you might just make bank during college. If you follow this, you're pushing yourself as a managerial sort of person rather than someone who actually works. Prepare to stagnate in the future unless you're very lucky or switch to the 0.1% working class.
If you think that's all a load of bullshit, then don't participate in anything. Keep your head down and work on personal projects. Asking for help from your teachers is usually a bad idea because they will try to take credit for your work, and might even make you write a paper citing you as the "student help" and themselves as the actual brains. Just keep your grades up and don't fail. Work your way through a shitty internship (or a really good one, if your projects are great) and you MIGHT be able to hop jobs effortlessly with a very decent salary.
Also, remember that everyone in college is a shithead. The bottom 80% bhangis of your 12th class are the only people that attend your college and are the only people you'll ever hear words of advice out of. Remember, they don't even have the brains to ask for help and couldn't comprehend this post even if they wanted to. Don't listen to them. The committee members are filling their quotas, the department heads try to act as if they're making things happen and the janitors are the only people that do any real work.
Also, if you think the boys are incompetent, the girls are worse. Don't be enticed by them and don't waste your time. Nobody from college will give a shit about you after you graduate because college is mostly about proximity in a dense, soul-sucking system than actual relationships (of ANY kind).
(Colleges under the same curricula are segregated into tiers, don't get memed into selecting a shitty stream for prestige)
