QAM Assessment & Combos
Everything, back to back, on the clock.
PremierQAM Assessment
The full test: mental math, probability, sequences, order books, trading P&L, and Bayesian reasoning rotate in one timed run. Ends with a percentile profile across every category and your best-fit interview tracks.
Core + Trading, back to back.
PremierCombo-10
The 5 Core games plus Market Making, Mental Order Book, Trading P&L Sprint, Conditional Probability, and Kelly Criterion — one round each.
Everything that computes an answer.
PremierCombo-15
Combo-10 plus Fermi Estimation, Bayesian Updating, Logic Deduction, Optimization Challenge, and Game Theory — the full 15-game run.
Trading & Reasoning
Quote a bid and ask. Wear the risk.
PremierMarket Making
Post a bid/ask spread against a hidden fair value. Counterparties trade against you — a tight, well-centered quote wins; a wide or mispriced one loses.
Read the book, fast.
PremierMental Order Book
A live bid/ask book flashes on screen. Spread, mid price, walk-the-book fill price — answer before time runs out.
Buy here, sell there, mark it now.
PremierTrading P&L Sprint
Track a rapid sequence of buys and sells at an average cost basis, then compute realized, unrealized, or total P&L before time runs out.
How many piano tuners are in Chicago?
PremierFermi Estimation
Order-of-magnitude estimation questions. You don't need to be exact — you need to be in the right ballpark, fast.
Fair coin, or biased?
PremierBayesian Updating
Start at a 50/50 prior, observe a sequence of flips, and update to the correct posterior probability.
Follow the clues to one answer.
PremierLogic Deduction
Short constraint puzzles — three or four clues, one valid conclusion. Interview-style logic, not LSAT-length.
Monty Hall and friends.
PremierConditional Probability
The probability questions people actually get wrong: conditional probability, Bayes, cards without replacement, Monty Hall.
How much of your bankroll?
PremierKelly Criterion
Given an edge and the payout odds, compute the Kelly-optimal fraction of your bankroll to bet.
Which bet actually pays more?
PremierOptimization Challenge
Two bets, one choice. Compute the expected value of each and pick the one that actually maximizes it.
What's your best response?
PremierGame Theory
A simple payoff matrix and an opponent's move. Find the row that maximizes your payoff against it.
Blink and you'll miss it.
PremierRapid Graph Interpretation
A bar chart flashes on screen, then disappears. Recall the max, the min, or a specific value from memory.
Correlation isn't causation.
PremierData Intuition
Short scenarios testing statistical intuition: confounders, sample size, R², and the causation trap.
Is it worth paying to know?
PremierInformation Value
A bet, and a price to learn the outcome in advance. Decide whether the information is worth more than it costs.
Binary search, but it's a game.
PremierQuant Guessing Game
A hidden number 1-100. Each guess tells you higher or lower — find it in as few guesses as possible.
