FAQ

What does "trial" mean here?

Each of these is a full-length, real-format simulation of one firm's actual online assessment — timing, question mix, and scoring rules included. It's a trial in the sense that it's one fixed sample: the same question set every time, for everyone, so you can size up the format before you commit real prep time to it.

Why is it always the same questions?

So scores are comparable between attempts and between people, and so the web free tier stays a step below the TradeMind app — which regenerates a fresh, realistic set every day. Every trial page has a "want a fresh set every day?" link that explains this and opens the app download.

Which one should I start with?

If you don't know your target firm's format yet, start with CTC — it's the broadest, mixing numerical, spatial, verbal and logic sections. Otherwise go straight to your firm: Flow, Maven and SIG each have distinct timing and penalty rules worth getting a feel for before test day.
