# 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

You are allowed to change your answers and there will be no checks that you're not cheating. Once you're done click on the finished page to see your score. Answers with a decimal part always require a leading token (which can be zero) and the decimal sign is the dot. There is no thousands separator. Examples: 0.001 10.3 34. Once you're done the score is to our twitter feed.
