I was about to join B.Sc in nursing but heard that it is not a good course & doesn't offer good salary. Is it true?

Yes, exactly. Let me tell you, in these days people consider nurses on contract bases, they don't have a proper job for long time so that's why it is not a great course and yes, the way doctor treat nurses and other department is pathetic, if you want to do something in medical then go with dietetic

Yes, that's right, but it is in India only, but in other countries there is no any discrimination in job of nurses and doctors and so. They all are treated equally.
