You can, as of about a year ago, take official SAT practice exams for free in Google Gemini.

SAT prep is much more than just taking practice exams.

The person to whom I responded seemed to imply that it consists chiefly or entirely of taking practice exams. I merely wish to point out that if you want your kid to take SAT practice exams every month you can do it for free at home.

		Such a "SAT test prep course" is going to involve more than just self-guided practice exams. It'll include feedback and coaching to address deficits revealed by those practice exams.
