AlphaStar Academy has recently published a practice test book for the upcoming AMC 10 competition:
https://www.amazon.com/dp/B08RYCLS4R
It contains four practice tests with solutions. The problems were originally written by many AlphaStar/A-Star faculty in the past and very recently improved with the goal of aligning them with the AMC 10 exams of 2020’s.
If you would like to take the same tests online and have access to the solution videos, check the self-study course option here:

We would like to wish all the students best of luck in the upcoming contest season.
