I was always told that the course books were all you need in order to take the exams and pass them, however, it seems like this course's books are fairly short in the amount of information within the text under the slides. I'm comparing this to the SEC504 I took in September last year. For those of you who took this, what should I do? Should I focus on the material in the books, make my index, and just hammer away in the workbook labs and just understand how each of the labs are working? In particular, I'm very worried about AJAX and some of the SQL (SQL not as much as AJAX, but I'm COMPLETELY lost on AJAX) Should I grab another book? I know I can and should look at w3schools for things I don't understand, and I will.
