What is the mouse drag test?
A mouse drag test measures how accurately and smoothly you can drag an object into a target and release it there — the skill the dragging section of a computer-based aptitude test (CBAT) is built on. On soexam.learnoscale.com the free test gives you 30 rounds in a horizontal, vertical or free-axis mode and reports your average time per drag, your accuracy (drops that landed in the ring), your path efficiency (how straight your route was), your consistency and your throughput in bits per second under Fitts's law. A good result is above 90% accuracy with an average drag under 1.5 seconds and path efficiency above 85%. It runs in the browser with nothing to install and no account needed to practise.
How to use the mouse drag test
Pick a mode
Horizontal and Vertical lock the handle to one axis. Random frees both and is the hardest.
Press and hold on the handle
The clock for that round starts the moment you press, so move as soon as you have it.
Drag it into the ring and let go
The drop counts when the handle's centre is inside the ring. Release outside it and the round logs an error, and you try again from wherever you dropped it.
Read your analysis
You get your average time per drag, accuracy, path efficiency, consistency and a drawing of the route every drag actually took.
Tips to get a better score
- Hold the button with your thumb side of the finger and move from the elbow. Pressing hard with the fingertip is what makes a drag wobble.
- Go fast for the first three quarters and slow for the last quarter. One deceleration beats three corrections.
- If your path efficiency is below 80%, your sensitivity is too high for the ring size — lower the DPI before practising more.
- Turn off Enhance pointer precision on Windows. Acceleration means the same hand movement travels a different distance depending on how fast you made it, which is fatal to a drag.
- Lift nothing. A drag broken by the mouse leaving the mat is logged as an error, and on a real CBAT it is a lost mark.
- Practise Random last. Horizontal and Vertical build the straight line; Random tests whether you have it.
Questions and answers
What is a mouse drag test?
A mouse drag test measures how accurately and smoothly you can press on an object, drag it into a target and release it there. It scores the whole movement rather than the click at the end, so it measures control under a held button — the skill the dragging section of a computer-based aptitude test is built on.
What is a good score on a drag test?
Above 90% accuracy with an average of under 1.5 seconds per drag and path efficiency above 85% is a good result on Standard precision. Under a second per drag at above 95% accuracy is very good. Accuracy below 75% usually means your sensitivity is too high for the ring size rather than that you need more practice.
What counts as an error?
Releasing the mouse button when the handle's centre is not inside the ring. The handle stays where you dropped it, so you can carry on dragging from there — but the error is counted and it resets your clean-drop streak. Running out of the arena is not an error; the handle simply stops at the edge.
How is the drag score calculated?
Your score is a hundred times your average throughput in bits per second, reduced by the square of your accuracy and by how straight your routes were. Throughput is Fitts's law: the index of difficulty, log2(distance / ring width + 1), divided by how long the drag took. Because it is an average rather than a total, a ten-round run and a fifty-round run compare directly.
What is path efficiency?
Path efficiency is the straight-line distance between where a drag started and where it ended, as a percentage of the distance your pointer actually travelled. 100% is a perfect straight line. A low figure means the hand is wandering or overshooting and correcting, which is a sensitivity and acceleration problem with a settings fix, not a practice problem.
Is this the same as the RRB CBAT dragging test?
No. This is a free practice tool for the underlying skill, not a replica of any official test, and your result here is not an official score of any kind. It is built to train the same movement — press, drag along an axis, release inside a target — under the same pressure of a fixed number of rounds.
Does it work on a laptop trackpad or a touchscreen?
Yes, both work. A trackpad drag is a genuinely different movement from a mouse drag and usually scores lower, so results are stored with the pointer type they were made on rather than mixed together.
Do I need an account to practise?
No. The test on soexam.learnoscale.com is public and needs no sign-up. Signing in saves each run, so you get a history, your personal best, your trend over time and a place on the leaderboard.
