Now listen to my sincere words child as you know that the  financial condition of your family is not good then don't go for expensive studies which your father could not afford as he will feel depressed and will curse himself of not being able to make his son go for expensive studies.

Now you can do one thing in which ever city you live get admission in b.sc. .
Note :never think that b.sc is easy and it doesn't have any value. It is more valueable than b.tech.

A m.sc qualified student can teach a b.tech student but a m.tech qualified student cannot teach a b.sc. student.

Don't run along with crowd as your friends might be doing only running behind engineering(jee,kota mein padunga) .Nowadays engineering has only become a graduation degree and nothing more than that.

If you really want to help your family then go for b.sc..
After b.sc you can either apply for m.sc. and become a teacher or you can prepare for any government jobs or civil services.
