How to Prepare for Casper (2026-27): An Honest Plan

Start with the test administrator's own free practice test — Acuity Insights gives every applicant an unlimited, full-length practice run inside their account, plus sample scenarios and webinars — and then, if you want more than one pass at the format, train under the published constraints: 3.5 minutes for two typed answers and one minute per video answer. Test takers consistently report no do-overs on a recording, and Acuity does not publish that rule, so our sim enforces a single take to match what candidates describe. That's the whole strategy. Everything below is the order to do it in and the traps reported by people who tested before you.

One thing first, because most prep sites bury it: Acuity does not endorse third-party prep — including this site — and states that its "research shows third-party coaching and prep can hinder your test score." We're not going to pretend that sentence doesn't exist. We'll tell you what we think preparation can honestly do, and what it can't.

Start with Acuity's free material. Really.

The official practice test is the only practice that runs in the real interface, with the real account flow you'll use on test day. It's free, it's unlimited, and skipping it to go straight to a paid tool — ours or anyone's — is doing prep backwards. Do a full official run early, before any drilling, and let it show you which of the two sections actually hurts.

What the official practice test doesn't do is remember anything. It's unscored and no feedback is saved — you finish, and there's no record of how you did to learn from. That gap, not a replacement for the official run, is what third-party practice is for. Ours is a AI-scored practice sim built on the current 11-scenario format: every answer scored 0-100 against the nine competencies, with what worked, what to fix, a rewritten example line, and a record of every attempt. A stopwatch and a friend can give you the clock; nothing but this gives you the feedback.

What Casper prep can and can't do

Be skeptical of anyone certain in either direction. Ask test takers whether Casper prep helped and you get a real split: people who barely prepared and landed in the top quartile, and people who drilled for weeks and swear by it, and both camps show up every cycle. There is no answer key to study for — responses are rated by trained human raters against everyone who took your test, and there's no official difficulty scale, no per-topic breakdown, and no score to see afterward beyond a quartile.

So here's our position. Preparation can't teach you to be a better person by Thursday, and any tool promising a quartile is promising something no one can deliver — ours included. What preparation demonstrably can do is remove the mechanical failure modes: not knowing the format, blanking on a video answer you can't redo, and — the single most reported problem on the typed section — running out of clock mid-sentence. And it can do one more thing, which is newer: put a score and two concrete fixes on every answer you write, so the fifth attempt is measurably different from the first. Familiarity with the constraints is most of what "prep" honestly means for this test. That's a narrower promise than the industry makes. It's also the true one.

A prep plan that matches the actual test

The 2026-27 test is 11 scenarios — 4 video-response, then 7 typed-response — with 2 questions each, about 65-85 minutes end to end. Video answers get 1 minute each after a 10-secondcountdown. Test takers consistently report a single take, and Acuity does not publish that rule. Typed pairs share a single 3.5-minute clock. Work backwards from those numbers:

First: one untimed pass at the format. Read the full format guide, then take Acuity's official practice run. You're not performing yet; you're finding out where the time pressure lives for you specifically.

Then: drill the typed clock. For most people the typed section is the test. Two questions, 3.5 minutes, no spellcheck — and typos aren't penalized, which means polishing sentences is time you're stealing from your second answer. Practice deciding fast and typing plainly; our typed-section pacing guide covers the pacing math.

Then: the video-answer muscle. The camera rolls after a 10-second countdown. Test takers consistently report there's no re-record, and Acuity does not publish that rule, so practice one take anyway. The skill is composure plus a simple structure, not eloquence — the video-response guide has the drill.

Don't skip personal-experience questions. The 2026-27 mix isn't all third-party dilemmas: test takers consistently report "describe a time you…" prompts, and people who only rehearsed dilemma reasoning report being blindsided by them. Have real experiences you can reach for — a failure, hard feedback, a commitment you broke — without a script.

Finally: one full timed sim in the week before. Whole format, real clock, breaks where the real ones fall. The goal is that nothing about the pacing is new on test day.

How long does that take? Reported prep windows vary widely — some candidates walk in nearly cold, others practice for weeks — and the free stack many use (the official test, YouTube walkthroughs, a typing trainer) covers the familiarization layer either way. Long drilling calendars have visibly diminishing returns; this is not a knowledge test.

The traps people report every cycle

The same stories repeat on every forum thread, so treat these as the syllabus. Trusting a practice tool's score: third-party and AI practice ratings aren't calibrated to Acuity's raters, and candidates who coasted on high practice scores report the gap bitterly — use practice for timing and structure, not for validation. Typing-speed obsession: yes, slow typists report suffering, but a whole counter-camp lands fine on quality over quantity — a typing trainer helps up to a point and becomes displacement activity past it. Dilemma-only prep: see above. And rehearsed frameworks recited on camera: a memorized opener spends your sixty seconds without answering the question actually in front of you.

Logistics are part of prep

Casper runs on fixed dates, and Acuity's instruction is to book at least three days ahead — how booking works covers the mechanics and why your real deadline is your school's, not Acuity's. Three rules change how you prepare: you get one attempt per test type per cycle (retakes only for verified technical failures), so there is no "practice sitting" — every sitting is the sitting. Accommodations paperwork is due at least four weeks before your test, which for late bookers is the earliest real deadline. And on test day you're allowed blank paper, a pen, and a hardcopy dictionary — but no pre-written notes, and no AI tools: Acuity's proctoring treats detected AI use as a "Red Flag" reported to your programs.

Timings, section counts, and Acuity policies on this page come from Acuity's official pages. The claim that video answers allow only one take and no re-record is not published by Acuity; it is described here as consistently reported by test takers.
