Thanks for comments.
Alex, I understand your point. Do you think the following would be a good purpose for a textbook about cancer?:
"to find out the key features of cancer, biology of cancer and therapeutic mechanisms"
I think it is too general, is it fine? Of course as I postview, I will state many detailed questions. However I think rachel purpose is also too general for his own field of study!?
By the way, I sometimes forget some of my questions because they are usually too many. Is it fine to have lots of questions?
One last question alex, is it OK to set the timer for 30 minutes for a 200 pages book? I think it would distract me and making me hurry which is not good for my concentration?!
