On This Week's Skeptical Sunday:

• The test prep industry is a multi-billion-dollar machine built on manufactured anxiety — not better education. Companies exploit the fear that a single test determines your entire future, turning parental stress and student panic into a lucrative marketplace where confusion plus fear equals profit.
• The same corporations that create standardized tests often sell the prep materials to pass them — a staggering conflict of interest. It's vertical integration at its most cynical: they've engineered both the problem and the solution, and students pay on both ends.
• Standardized tests like the SAT don't predict college success as well as high school GPA does, and access to expensive prep widens inequality rather than leveling the playing field. Kids in the top 1% of income have a 1 in 4 shot at elite schools — kids in the bottom 20% have a 1 in 300 chance.
• Social media has supercharged test prep anxiety, turning studying into a performative competition. Students spiral comparing their materials and scores to strangers online, and prep companies profit without even advertising — the students do it for them through posts and affiliate links.
• You don't need to spend a fortune to prepare well. Start with official practice tests and free resources like Khan Academy, use proven techniques like spaced repetition and the Feynman method, and remember — one good resource used properly beats five expensive ones you never open.
