Is it a good idea to just read the entire programming-related book, assuming within your grasp of 250-400 pp.? Or take it slow and go through it taking your time trying to understand absolutely everything.
UPDATE 1: I am reading Beginning ASP.NET 4: in C# and VB
and Programming in Objective-C 2.0
and I found that I learn a lot more if I take my time reading the book even if I have to spend 1 hour on one page... but by the time I finish reading all will be clear to me and I won't have any questions. I tried to skim the book at first but I didn't remember anything the next day.
