Broad technology education is great, but if the main goal isn't getting you to pass the certification, you're in trouble. The course must be current. The course must include realistic testing dry runs. The only certainties in life are death and taxes. Check the school's references.
Every school sounds good in an advertising brochure.
Only former students can tell you if the course really delivers the goods. Experience is not enough. You need to know the right answers according to the book, not your experience. Don't give the answer you want-give the answer that the vendor wants. If that strikes you as unfair.
