About the course
This course consists of a number of assignments for you to check your knowledge of the basic vocabulary needed for the TOEFL. The assignments were created with SkyEng dictionary API.
The course is adaptive what means that you can not follow a linear pre-set structure of the course, the adaptive engine generates a unique path for each student.
In the course you'll have extra buttons on the top of the page like this:
The first button becomes active only after you successfully solve the problem. If the problem seems too difficult or too easy, you can click on one of the buttons on the right, the engine will take into account the knowledge level for future content recommendations.
Initially, the adaptive system may behave somewhat randomly for you, but the more problems you solve, the smarter it becomes!
