Anyone have any experience with the ACT prep classes they offer? I'm wondering if they are worthwhile or just a waste of time/money. I'm leaning towards "they can't hurt", but really have no idea.
Generally speaking... they work. The approach of the test and how the questions are written are quite different from what happens in school. An effective test prep class will greatly reduce the chances the student is surprised by anything on the exam.
Tough to give a general review of the national companies that offer test prep because those are operated by franchisees who have a wide range of skill level as instructors themselves and their ability to attract and develop effective instructors underneath them. In a vacuum I'd say Princeton Review's materials are more effective than Kaplan's and generally does a better job training instructors at the undergraduate level, but that can vary from city to city. Barron's has the edge reproducing the toughest end of the test questions but are useless for a low achiever trying to boost up to national average.
You can spend a wiiiiiide range of money on this. Might help to see if there's a specific goal from raising your ACT score, like qualifying for renewable instate tuition at a public university a ways away, or earning scholarship money at a school on your short list, or hitting the NCAA clearinghouse score for a D-I scholarship. Easier to get buy-in and engagement from the student if there's a specific bar trying to be cleared.
I'd advise against a one-off clinic or weekend standardized test prep boot camp. Some of these techniques and practices take time and repetition to sink in. I'd send the kid to a free practice exam before a one-day test prep clinic. Just about any worthwhile test prep company or tutor will offer free practice exams they will grade in general and break down by question type to highlight potential weaknesses. It's industry standard for the test to be offered for free, but having to sit through a sales pitch to get the score report. It gives off a bit of a "time share in south Florida" vibe, but that's the nature of the beast.
Some shops will offer some sort of "Score Increase Guarantee". Read the fine print. Usually that guarantee isn't your money back, but a free retake of the course. If you're breaking a tie between two shops to work with, go away from the one offering a guarantee. The better shop won't need to offer one.
So those are a few disjointed thoughts typed at different times between other tasks. If anything didn't come across clearly or was too inside baseball, don't hesitate to ask. I'm a couple years removed from working in test prep so I'm not up on the most recent changes to the SAT, but there are some parts of the business that haven't changed since it became a thing.
