Hey there.. even I jus enrolled in the course and I think going for the research option would be better rather than interviewing a physical therapist because that is more difficult. Also I have no clue how to go along with the research. If you have any clues please let me.

Thanks

Hi,
The book is really necessary because the first assignment is completely based on the chapters in the book. Well you dont need to buy you can rent it instead on www.chegg.com it will be cheaper compared to buying.
