Read full descriptionHide full description
Train for the real quant and consulting interview tests, then keep going into the interview that follows them. MindMath Pro rebuilds the actual numerical tests firms use, with their real timing and scoring. Run the Optiver 80-in-8, the Flow Traders 75-in-10 and the IMC 24-in-18, then see how your score compares with everyone else who took the same test. The online test is only the first round. Round 2 adds 40 probability and expected value questions from the interview that comes after it, covering expected value, waiting times, conditional probability, counting and the classics that come up again and again. They are untimed, because they are meant to be thought about, and each one comes with the full working rather than just the answer. Free to start, no account needed: Speed Benchmark. Two minutes, as many as you can, the standard mental maths speed score. One free run of each firm simulator (Optiver, Flow Traders, IMC). The first three Round 2 questions. Number sense drills for percentages, fractions, decimals, sequences and case math. Smart Practice, plus stats that find your weakest operation and send you back to it. An interview countdown plan from today to test day, and on into Round 2 prep afterwards. Pro unlocks the reps: Unlimited runs of every firm simulator. All 40 Round 2 questions with full worked solutions. Hard and Quant difficulty. The full tricks library and advanced analytics: average answer time, weakest times-tables and one-tap weakness drills. Unlimited daily volume. Free is capped at 30 problems and 3 sessions a day. Seeing a question once does not make you faster, but doing five hundred does. The free app shows you the gap. Pro is how you close it. Pricing: weekly, monthly and yearly plans, and a one-time Interview Crunch pass that unlocks everything for 30 days with no auto-renew, for when your test is close. Subscription details: MindMath Pro offers auto-renewable weekly, monthly and yearly subscriptions, plus a one-time 30-day Interview Crunch pass which does not auto-renew. Prices, and any free trial for new subscribers, are shown in the app before you pay. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your Apple ID is charged for renewal within 24 hours of the period ending. You can manage or cancel anytime in your App Store account settings.

Merchant Navy Aptitude Test
Read full descriptionHide full description
Everything a deck officer gets tested on, and everything a cadet faces before they get there. 35 training modules covering bridge watchkeeping, navigation, the Rules of the Road, signals, engine-room reasoning and the aptitude papers used in cadet selection. NOT A FIXED CARD DECK Most maritime study apps hand you a set list of questions to memorise. This one builds every item from the underlying rules. Light fits come from the COLREG light rules, buoys from the IALA system, circuits and gear trains from physics. Run a module twice and the questions are different. Nothing can be learned by rote. WATCHKEEPING (8 modules) Bridge Watchkeeping: hold detection accuracy across a full 10-minute watch, where fatigue is the real opponent AIS Target Stream: routine traffic streams past and the pace quickens; react only to the rare distress signal Target Count Buoy Comparison Bridge Console Radar & VHF Helm & Calculation Traffic Priority NAVIGATION (5 modules) Relative Motion: judge CPA, TCPA and bearing drift straight off the radar picture, then hold the skill when the display flips from north-up to head-up Chart Grid Relative Bearing Compass & Chart Work Passage Planning RULES & SIGNALS (6 modules) - Rules of the Road: crossing, head-on, overtaking and the Rule 18 hierarchy, by day and from lights alone at night. Every scene carries genuine risk of collision and exactly one defensible call - Navigation Lights & Day Shapes: who is she, what is she doing, which way is she heading - IALA Buoyage: laterals, cardinals, danger and safe-water marks in both Region A and Region B. The red/green flip is the classic trap; drill it until it is automatic - Sound Signals: whistle signals by ear, synthesised live. Hear it, count it, name it - Signal Alphabet & Flags: five layers per token, flag, letter, phonetic word, morse and meaning, with Aldis-lamp morse and hoist decoding - Colour Vision: practise the plate-reading format, every plate generated fresh so nothing can be memorised ENGINE ROOM (2 modules) - Mechanical Comprehension: animated gears, belts, tackles, levers, rams and ramps. Every distractor is a classic mistake - Electrical Comprehension: which lamps burn, which burns brightest, what a blown fuse takes down COMMS & CODES (5 modules) - Position Report Recall β’ Radio Read-Back β’ VHF Traffic β’ Identity Check - Code Matching EXAM CORE (9 modules) - Mental Arithmetic, Number Series, Matrices, Logic & Reasoning - Verbal Reasoning, Reading Comprehension, Tables & Charts - Cube Rotation, Cube Folding The spatial, numerical and verbal items that academy and sponsorship papers still use. Not seamanship, but it is in the exam, so it is in the app. CHOOSE YOUR ROLE Tell the app whether you are heading for the deck, the engine room or a traffic-monitoring seat, and the modules that matter most come first. Change it whenever your career does. WORKS AT SEA Everything runs offline. No account, no sign-up, no connection required. WHO IT IS FOR Deck cadets and officer candidates preparing for academy entrance and shipping company selection. Watchkeeping officers refreshing the rules before a revalidation. Marine engineers and ETO candidates working through mechanical and electrical reasoning. Anyone preparing for a naval or traffic-monitoring selection battery. The Colour Vision module is screening practice only. It is not a medical test and cannot replace an official examination; screen calibration and ambient light both affect results. Not affiliated with, endorsed by or connected to any maritime university, administration, shipping company or certification body. Module content is written for study and does not replace official publications.
