SAT Advice (General) Post

Others have aptly pointed out that even after 15 years of vigorous expansion (and a few contractions due to budget challenges), it's still a stretch to call Khan's extensive library of videos an "academy," when there is zero real-time instruction offered.
Khan Academy's instructional videos are now narrated not only by Mr. Khan, but by a variety of instructors across the world, and they vary widely in quality, further exposing the weaknesses of the static video format for education. You might feel smarter after watching a video, but this type of learning is more passive than active, and studies have shown that active learning leads to significantly greater retention. You can’t ask questions of a video, for example—which, to be fair, is more of an inherent limitation of the video format itself than a criticism of Khan Academy in particular.
This phenomenon is sure to continue with the advent of the digital SAT aka DSAT—which has 56 fewer questions than the paper exam (98 vs 154), meaning that each question will be worth more points on average than on the old paper SAT.
These types of misinformed, anonymous online comments tell me that the commenters aren’t actually taking the tests—because to any objective observer who understands the material and is actually paying attention, the current version of the SAT is significantly tougher than it used to be. That's just what happens as a standardized test becomes more established: 1) information about the exam is shared, 2) overall scores go up, and then 3) test difficulty must increase to compensate. This is true not only for the SAT, but also for other popular standardized exams such as the ACT, GRE, GMAT, and LSAT: they are all growing in difficulty over time.
