CORE TRAINING

FIRM-STYLE OA PRACTICE
Run timed, independently created practice routes inspired by publicly described formats associated with CTC, IMC, SIG, CCI, and Wincent. Practice numerical, spatial, verbal, logic, pattern-recognition, valuation, and decision-making skills. Selected daily mock tests and sample OA sections are available free. Each mode shows its access rules before you start. Pro unlocks all firm mocks, complete OA routes and practice modes, including unlimited freshly generated firm-mock papers.

MENTAL MATH & APPROXIMATION
Train integers, decimals, fractions, percentages, powers, rapid estimation, Taylor approximations, and the Rule of 72. Build speed with targeted drills and full timed sets.

SEQUENCES
Practice arithmetic, geometric, Fibonacci-style, alternating, interleaved, and look-and-say patterns with configurable difficulty.

PROBABILITY & EXPECTED VALUE
Work through combinatorics, Bayes’ theorem, cards, dice, poker odds, and fast expected-value decisions.

MARKET MAKING
Choose Play or Pass from expected value, then practise quoting two-sided markets against an adaptive counterparty.

OA PREP & COGNITIVE GAMES
Train with 16 original games covering working memory, attention, task switching, planning, risk tolerance, and decision-making under uncertainty. Review a clear multi-dimension profile after each battery.

BRAIN TEASERS & KNOWLEDGE
Study a growing library of worked quant interview puzzles and reference guides covering interview strategy, probability, stochastic processes, options, Black–Scholes, and machine learning in quantitative finance.

ANALYTICS & DAILY GOALS
Set a Daily Goal and review accuracy, response time, activity history, streaks, and per-question mistakes to focus the next session.

REVIEW YOUR PRACTICE

Review correct and incorrect answers after a completed drill and revisit saved sessions in History. Available worked solutions appear alongside the question and answer. Account history can recover available explanations from saved records, so you can return to your review later.
