The TOEFL Essentials is a shorter exam that can be taken completely from the comfort of your own home. It’s also graded on a scale of 1-12 and has five sections instead of four.\r\rThe TOEFL iBT is usually taken at a testing center and the highest grade is 120, excluding one section of the test, and it takes almost double the amount of time as the Essentials version. Most schools will ask for the iBT version.
