Easy level
This level has a single operation per question and the terms are at most 4 digits (including decimals).
All answers have 4 digits or less. This is (much) simpler than a real trading test. If you want you can
also try this level as a test (posts to
!) or set up a
custom exercise.

Medium level
This level has a maximum of 4 operations per question and all terms are at most 5 digits including the decimal part.
All answers have 5 digits or less. This is about the level of some trading tests. If you want you can also try this
level as a test (posts to
!) or set up a
custom exercise.

Hard level
This level has a maximum of 6 operations per question and all terms are at most 6 digits including the decimal part.
All answers have 5 digits or less. This is beyond the level of most trading tests. If you want you can also try this
level as a test (posts to
!) or set up a
custom exercise.

Scoring
You get one point for every correct answer. Deduct one point for each error. If you skip a question or run out of time in a timed test, all following questions are not used in your score. Time yourself to 6 seconds per question. Generally you need to pass 55 out of 80 questions or ~70% of the maximum score, but higher is always better.
Manual
The answer to the test will be printed right next to it in the site's background color. You can use CTRL+A, Command+A or use
the mouse to select all text on this page.
