An acquaintance of mine runs a high end SAT training program. He gets these results reliably for folks who have had little or no preparation before coming to him. Trained test takes is in the hundreds (maybe more).

Is this data or anecdata? You be the judge. He finds it easy to bank on professionally.

I encourage you to talk to someone who has worked at a high-end SAT training program (not Kaplan or that type). They can tell you the real deal, both successes and failures. Don’t rely on talking to the businesses themselves, because they will be selling their services rather than telling the complete truth (unless you know them personally).

Fwiw, failures are usually due to one of a few factors:

1. anxiety

2. learning blocks

3. physical issues (e.g., lack of sleep, sick, etc.).
