My son participated in the PSAT training course this summer (2024). The primary teacher was absolutley fabulous; however, the sub (for 2-3 of the 8 sessions) was extremely disappointing. In comparison, the courses were much less rigorous and time on task was inconsistent. Not only were breaks longer but also the time used to solve a problem was unnecessarily extended. Mistakes were made, time was not well spent (as corrections had to be made) with little confidence and an inability to maintain a captive audience. The overall quality was substantially lower. I feel the sub was not well vetted to lead the classes--from auditory value, tech skills, and content proficiency. For a four week summer course that required dedication and focus from a teen son, I’m very disappointed in the shift to a sub and am much less satisfied with the overall quality of the course.
