Comparing your performance on the SAT to all other SAT test takers’ is a fairly general way to look at one thing: to get into a good college.
Although 2018 Dec. SAT curves looked very bad both in US and in Asia, Belina (KC G11, who took SAT intensive training at RR since 2018 Oct.), Heidie (AAIA, 新北美國學校, G10, who took 2018 Summer SAT program at RR) and Ian Chen (KC, G12, who also took partial 2018 Summer SAT program at RR) they still scored well in Dec. SAT.
For ACT, Natasha took 2018 summer ACT private training at Red Rock and Doris is a year-long ACT student at RR. They both scored well too and will definitely use it in their college application.
Congratulations.
