$MIT integration bee qualifier test MIT Integration Bee Qualifier Test 2020. Check out Brilliants new interactive math courses today! Use this link https://brilliant.org/blackpenredpen/ to receive 20% off. We will do the 2020 MIT Integration Bee qualifier test. This is the test for the people who want to compete in the actual Integration Bee. You would need to know (at least) all the standard integration techniques from calculus 1 and calculu2 such as integration by parts, u sub, trig sub, partial fractions, improper integrals, and more. You may occasionally need some famous results such as the Gaussian Integral, some reduction formulas, symmetric formulas, and more. This test has 20 integrals and you only have 20 minutes. I believe you do not have to show your work and you do not need to put down the +C for indefinite integrals.
