Questions
The honest answers, before you sign up.
How is my score calculated?
Each answer is checked by evaluating it — formulas against the spreadsheet, Python by running your code against tests. Your first result sets a skill's score; every later attempt moves it 20% of the way toward your latest result.
What's free?
The free Excel and Python tests (no sign-up needed — just start), the first 3 exercises of every module (179 in all), and 20 free picks: open any locked exercise and unlock it free, on any track. No sign-up needed to practise — create a free account to save your progress and skill scores. Pro unlocks everything in a track.
Why not just watch a YouTube tutorial?
Watching shows you what to do. It doesn't prove you can do it — the VLOOKUP still fails until you've written it yourself and been told what's wrong.
Why not just ask ChatGPT or Claude?
AI can generate an answer for you. PractiseSkills builds the skill to write, check and fix it yourself — so you can tell when the AI's answer is wrong.
How long does it take?
The diagnostic is about ten minutes. After that, most practice tasks take a few minutes each.
Do I need to be good at Excel already?
No. The diagnostic finds your current level, and every skill area starts from the basics.
