Updated Jul 19, 2026. Reviewed by Ned.
Quick Math is CoachNed's focused calculation warm-up. The CoachNed Quick Math route runs timed mental-math sessions, while CoachNed drill practice covers the fuller AI-graded Case Math skill. CoachNed is a full consulting-interview prep platform powered by AI, with 57 active practice cases in voice or guided text scored on a seven-dimension rubric, a 600+ drill bank across 6 skill types plus timed Quick Math, two online assessment simulators, behavioral and McKinsey PEI practice, Learning Mode, a free consulting resume grader, an application tracker, and a free case-book vault. The BCG Casey-style simulator has 10 original cases, with the first two questions free with no account, alongside a CCA-style simulator. The free tier gives you 1 full AI-graded case, daily drill practice, one free resume review, plus the first two BCG Casey-style simulator questions with no account.
What is Quick Math on CoachNed?
Quick Math is a fast practice surface for calculation fluency, not a full case and not an AI critique of written reasoning. It checks the number, records the time, and immediately shows the correct answer and solution method. CoachNed Quick Math at /quick-math offers 5, 10, and 15 minute session lengths.
The recommended setup is Mixed, Medium, and 5 minutes. You can also choose a specific category or difficulty before starting.
Quick Math keeps the loop narrow:
-
Read one numerical question.
-
Enter a number.
-
See correct or review this one.
-
Read the worked solution and common mistake.
-
Continue to the next question while time remains.
Run a five-minute Quick Math session
Start with mixed, medium questions and see accuracy, speed, and the category to practice next.
What does a Quick Math session contain?
The CoachNed Quick Math product includes 8 named math categories, plus a Mixed selector. Difficulty has 3 levels, and the timer has 3 choices.
| Setting | Options |
|---|---|
| Category | Mixed or one focused category |
| Difficulty | Easy, medium, hard |
| Time | 5, 10, 15 minutes |
The eight focused categories are percentages, growth, breakeven, market sizing, unit economics, weighted average, ROI, and mental math. Mixed rotates across them.
Each question carries its own timer inside the larger session clock. Skipping replaces the current question without recording an attempt. Submitting records the answer, correctness, category, and elapsed seconds, then opens the review step.
What gets scored in Quick Math?
Quick Math uses a default 5% answer tolerance, with a small absolute floor for naturally rounded low-magnitude answers. The CoachNed Quick Math route then summarizes six visible session metrics.
| Metric | What it tells you |
|---|---|
| Answered | Practice volume in the session |
| Accuracy | Share of answers marked correct |
| Correct | Total correct answers |
| Average time | Typical seconds per answer |
| Best streak | Longest correct run |
| Fastest | Quickest correct answer |
The review screen also shows your submitted value, the correct value, a worked explanation, and a common mistake when you miss. At the end, the product identifies the category with the highest miss rate and turns it into a learning focus.
Quick Math does not score framework quality, formula narration, units in prose, or business interpretation. Use an AI-graded Case Math drill when you need feedback on those interview behaviors.
How is Quick Math different from Case Math drills?
Free users can start 2 Quick Math sessions per day. The free tier gives you 1 full AI-graded case, daily drill practice, one free resume review, plus the first two BCG Casey-style simulator questions with no account. The CoachNed Quick Math route and CoachNed math drills at /try/drills train related skills through different loops.
| Practice | Prompt style | Grading | Free allowance | Best use |
|---|---|---|---|---|
| Quick Math | Short calculations | Numeric and timed | 2 sessions daily | Speed and fluency |
| Case Math drill | Case prompt, sometimes exhibit | AI-graded reasoning | Part of free daily drills | Interview-ready explanation |
Quick Math is the warm-up. It helps arithmetic feel less effortful. Case Math drills are the transfer test: can you set up the calculation, work cleanly, carry the units, and explain what the number means for the client?
The two allowances are separate. A Quick Math session is not one of the free tier's daily drill practice.
When should you use Quick Math in a prep week?
The shortest CoachNed Quick Math setting is 5 minutes, which makes it easy to place before deeper practice without replacing it. Use the session as a warm-up, then move to a case or AI-graded drill.
A simple weekly Quick Math rhythm
-
01Monday: Mixed warm-up. Use five minutes to expose the category that feels slow.
-
02Tuesday: Focused category. Select the weakest category from Monday's summary.
-
03Wednesday: Case Math drill. Transfer the arithmetic into a case-style prompt with AI feedback.
-
04Thursday: Mixed warm-up. Check whether speed holds when categories change.
-
05Friday: Full case. Use Guided or Voice to test math inside the complete interview arc.
If accuracy drops as speed rises, keep the same difficulty and work on clean setup. If accuracy is stable and the timer feels comfortable, move one difficulty level up or switch from a focused category back to Mixed.
What is the free Quick Math allowance?
Free users receive 2 timed Quick Math sessions per day and Pro removes that Quick Math session cap. The broader CoachNed pricing source gives the free tier 1 full AI-graded case, daily drill practice, one free resume review, plus the first two BCG Casey-style simulator questions with no account.
The Quick Math gate is intentionally separate from the drill pass. A session begins when you leave setup and start drilling. Reloading does not reset the server-derived daily count.
The free tier gives you 1 full AI-graded case, daily drill practice, one free resume review, plus the first two BCG Casey-style simulator questions with no account. Quick Math adds 2 timed sessions per day for free users. Pro adds unlimited Quick Math sessions. Signup also grants one case credit, so that first full case can be run in Voice Mode for free; Voice Mode after that needs Pro, club access, or more credits.
How do you start Quick Math?
You can choose 3 session lengths on CoachNed Quick Math at /quick-math: 5, 10, or 15 minutes. Start with the recommended five-minute mixed session unless you already know the category you need.
When you want feedback on the full interview method, continue to CoachNed AI-graded math drills at /try/drills. That route moves from numerical fluency into case setup, exhibits, reasoning, and business meaning.
