I guess it's better to make a decision now rather than in five years. For the doctor-is-good argument, one could also say that there are far less good CSPs in the country than there are good doctors, and that a CSP can make a far greater contribution towards the society than a doctor can. But being a CSP without wanting to be one (as your post suggests that you want to do css just to make your parents happy) can only make you worse off......

and if you do want to do css even after the mbbs, it's perhaps better not to deny the seat to someone who really wants to practice afterward :-)

but again.... mbbs can be a good fall back plan if anything bad happens on the way to becoming a CSP......

but once again...... fall back plans tend make you weak - burnt boats can sometimes be a great incentive!
