Most people prep for quant mental math tests by grinding Zetamac randomly and wondering why they plateau. FlashQuant fixes that with a structured approach: build your fundamentals first (times tables, addition facts, complements to 100), follow a clear milestone progression, then train under timed pressure. It's built specifically for people preparing for quant firm tests like Optiver's 80-in-8, Jane Street, Citadel, and similar OAs.
