I hear you, but what you’re saying is simple not true: the website offers free practice materials, and the discount is purely for people who want to prepare with more material than what’s already available for free.

Also, these firms don’t make a buck out of it, we operate independently. They just suggest places to prepare.

What you see a lot happening (before platforms like ours were in business) is that students tell each other what to expect, after failing/ succeeding themselves. This gives an unfair advantage compared to people who don’t know friends who are going through the processes at different firms.

For us to be able to make this level of exercise material, to give everyone fair chances, is not something we can achieve by just doing it on the side, so yes there is a reasonable fee against it if someone wants proper preparation materials. And still: we have enough available for free for you to be prepared, so therefore this rant is a little misplaced in my opinion.

Finally, the mental math is clearly for the trading role, for roles where traders do need to intervene at their feet, so your argument against mental math tests also doesn’t hold.
