If you've ever seen a chess rating, you already know the appeal: one number that means more the longer you play. The Mastery Rating in AccelaStudy® AI borrows that look, a single score on a long scale, but it is a different calculation. Your Mastery Rating is worked out from your proficiency in the course, the same evidence-based number the rest of your progress screens already show.
We built it for a simple reason: percent-complete progress bars are useless for measuring whether you can pass an exam.
The problem with progress bars
A 40-hour course at 87% complete tells you almost nothing. It tells you you've watched videos. It doesn't tell you whether you'd get the question on burst credits right. It doesn't tell you which 13% you skipped, or whether the 13% you skipped happens to be the part the exam loves.
We wanted a number that meant something. The shortlist of things the number had to do:
- Be continuous. Pass / fail is too coarse. Five buckets is too coarse. You learn in increments.
- Follow evidence. It moves with what you show you know, not with how long you've been logged in.
- Be readable at a glance. A number, plus a named level, so you don't need to know any math to use it.
The nine levels
Your Mastery Rating runs from 400 to 2,200. We group it into nine named levels, so you can see where you stand and how far the next level is:
| Level | Name | Mastery Rating |
|---|---|---|
| 1 | Starting out | 400–799 |
| 2 | Explorer | 800–999 |
| 3 | Builder | 1,000–1,149 |
| 4 | Solver | 1,150–1,299 |
| 5 | Strategist | 1,300–1,449 |
| 6 | Advanced | 1,450–1,599 |
| 7 | Expert | 1,600–1,799 |
| 8 | Master | 1,800–1,999 |
| 9 | Ace | 2,000–2,200 |
Every course has its own rating. Your Dashboard shows it on the course card with your level, and it shows how many points you have left to reach the next one.
What moves it
Your Mastery Rating follows your proficiency in the course. As you answer questions, work through lessons, and review what you missed, your proficiency changes, and your rating moves with it.
A few things fall out of that:
It starts as an estimate. Until you've answered enough questions in a course, we label your rating as an early estimate. The label goes away once there is enough evidence behind the number.
It isn't a pass prediction. Your Mastery Rating tells you how much of the course you've shown you know. Where a course supports it, your chance of passing the exam is a separate estimate, shown separately.
It's the same scale in every course. A rating of 1,300 means you are at Strategist in that course, whether the course is IAM or networking or algebra.
Why your number sometimes goes down
This is the most common confusion. People expect a study platform to be a treadmill that only goes up.
Your rating tracks your proficiency, and proficiency can slip. Two common reasons:
- You missed something you previously got right. The evidence about what you know just changed, and your rating changes with it. Annoying in the moment, useful in aggregate.
- You moved on to harder material and missed some of it. That's a probe, not a punishment. Until you try harder items, neither you nor we can tell how far your knowledge really reaches.
If your rating dips a little after a bad session, don't panic. One flaky session rarely changes the overall picture.
What to do with your number
A few practical reads:
- Look at the spread, not just one course. If you're a Strategist in compute, a Strategist in networking, a Builder in storage, and Starting out in security, the one weak area is the part that needs your attention.
- Don't grind where you're already strong. The next point is harder to earn the higher you go. Use that time on the course or topic where your level is lowest.
- Watch the trajectory before the number. A Builder who's been climbing for two weeks is going to outpace a Solver who's plateaued. Direction matters.
A proficiency number is only useful if it tells you something you didn't already know. That's the whole idea behind the Mastery Rating: a single score you can check, trust, and act on.
