The most recommended resource for preparation for Optiver's math test is tradertest.org. But the website is down. What are the closest alternatives to it?
Although this question has been asked on this forum before the answers were unsatisfactory because one or the following things were missing from the suggested alternatives:
Floating point: Integer operations are generally easier and I need practice for operations on floating point numbers.
Penalty for error: On some sites you can just keep typing numbers till you get the right answer. In a real life scenario you will just move on to the next question without knowing that the last one was incorrect. I want to know how many did i answer incorrectly
80 question in 8min format: This is not a necessity, but given the fact that optiver tests are genrally in this format it would be an added plus.
I basically want a site that is the closest simulator for Optiver's math test. So if there is any additional characteristics you know from your experience of giving the test kindly suggest a resource accordingly. If I have incorrectly assumed something about the test kindly correct me.
All this being said, I assume their test has a lot of variations accross countries or time, so I am only looking for the best estimate of what the test will be like.
Some websites that do not meet the above criteria are: rankyourbrain.com and arithmetic.zetamac.com
