Sequence Test

Hard level + non math sequences

This has more possible exercises than the hard level. The answers can have at most 4 digits. If you want to select which tests are used, you can set up a custom exercise.

Scoring

You get one point for every correct answer, unlike the math test there is no negative score.

Manual

The answer to the sequenence and it's explaination will be printed right next to it in the site's background color. You can use CTRL+A, Command+A or mouse select all to show it. Custom tests will offer more control over the test.
