315 minutes ( 15 minutes preparation, 300 or 5 hours testing time).
150 questions. Feb 24, 2022. Test location: Step Computer Academy. Must wait 30 days from the original test to retake the exam. When registering it, you have one year time to actually take the test. 在一年之内都可以考。I get my test result immediately, 255.
我没有好好准备。The test name, Middle Grade Mathematics, is misleading. I thought it is basically arithmetic questions. But it is not.
1. Many probability and statistics questions, venn diagram.
2. Many measurements, for example, one work take 3 people 6 hours to finish. One spend XXXX seconds, one spend 1.86 hours, the third spend 2 hours 45 minutes and 5 seconds. 运算量很大。
3. Many transformation questions.
4. Test asymptote . Not prepare for it.
