Throughout 2020-21, we expect that the SAT tests shall remain in "good' curves. Below is the curve and index update after the test on March 13, 2021.
Since 2016, SAT has gone through several curve period. March 2016 - June 2018 is the establishment period. During this time, the new SAT curve was initialized based on large scale real test results. The curve in each test synchronized with our curve index.
Beginning in June 2018, SAT curve fluctuated and was generally lower than its initial level. Students were punished by the test and often protested online. During this time, curve moves against our curve index. This is the beginning that our curve index was composed. We suspected there was artificial driver behind the lower curve in this period.
Curve in 2019-20 seemed coming up trend, but generally lower than in 2016-2018. Pandemic put a six month break to the test industry during March - July, 2020. Since its reopen, the curve has been rather stable and friendly.
