After studying some 46 subjects in bachelors, I don't really remember most of them(its been 10 years). They are kind of faint basics in mind. I completed my Masters some how coping with deadlines. Now there is Phd in a DIFFERENT subject. I have to first review my bachelor text books and then actually understand he phd topic, then start the literature survey.

Basically someone said "you need to have a solid working knowledge on your topic BEFORE getting into Phd"...if thats true, it will take me 3 more years to get ready for a phd..leave alone doing it.

Whats your thoughts?

It's much easier if you already know the background, but like you i had forgotten most of the detail. By the time you write your thesis you will know what you are talking about, so don't worry.

Yes you can. But ideally you should know the field well already before starting out. It's much easier that way (less time to read, more time to think, and a PhD is about thinking).

Yes I hear you friends. It makes good sense.
