hello there,hope you are doing well.firstly two things I want to tell you

you would begin your career as a fresher all over again from scratch.

Your degree and effort in Pharmacy, would be a compete waste

Till the time, you graduate and gain experience and begin working full fledged, your Pharmacy colleagues, would be well settled

Lastly, The LAW career especially related to property matters, though a very lucrative field, initialy requires a lot of struggle, maintaining contacts and you need to be an extrovert and more importantly a fighter.

Are you ready for all this.

If Yes, opt for LAW, or else, M. Pharm would be a better option

Choice is yours.
