Hi
Anyone taken the Optiver mental math recently ? I have searched all over the forums and
I have trouble finding out the actual difficulty level and the kind of questions that are in the real test.
The reason for question, all the popular sites have differenttype of questions.
As we know we are give 6 seconds per question in real test (80 questions in 8mins),

Rankyourbrain, I can score 18(2mins) in expert level

zetamac, default settings I can score 25 (2mins)> these questions are much easier and no fractions

there is another site I came across which seems/claims to have actual optiver test :
this is the most difficult test I have come across, and I am getting destroyed with a  score of 10 (8mins)
and this has very different kind of questions.

Any ideas which site has the questions that are closest to actual test and what should be my target on that site before I consider myself ready to apply ?

Thanks!

No site really similar to optiver. Look also for one named like Graduate trader math or something like that.

The most difficult questions are the ones involving fraction with the answer being a fraction multiplied by some factor.

Example:

3/4 * 48/21 = 84/49

So you have the real answer which is 12/7, but you will get crazy because looking at the answers you will not see 12/7 but 84/49, which is 12/7 multiplied by 7/7.

To pass you need to do at least 60 over 80.

Srsly if you don't see 12/7 you might as well don't be a trader, fraction reduction is the first thing you should learn in school
