Am I Ready? What Your Practice Test Scores Actually Tell You

· 4 min read

Every exam forum has a version of the same thread. "I'm averaging 72% on the simulator. Exam is in nine days. Am I ready?" Below it, a dozen replies: one person passed with 65%, another says don't sit until you're consistently over 80%, a third failed after scoring 85% on everything.

They're all telling the truth, which is the problem. A practice percentage on its own doesn't answer the question you're asking. It can be a useful signal, but only once you know what it's made of.

Five reasons one number misleads

1. You've seen the questions before. This is the big one. By the third pass through a question bank, a lot of your "correct" answers are recognising a question, not solving it. Scores on repeated questions climb steadily, and they measure your memory of the bank, not of the subject.

2. Banks differ in difficulty. Third-party question banks are often written harder or easier than the real exam, and differently in style. A score from one provider doesn't convert to another provider's, or to the real thing. That's why forums argue about thresholds forever: people are quoting numbers from different scales.

3. The average hides the weak area. 75% overall can mean 75% everywhere, or 90% on four topics and 40% on one heavily weighted topic. Those are very different positions. Many exams also report or weight results by domain, so a weak area can hurt more than the average suggests.

4. You might be right for the wrong reason. On multiple choice you can get a question right by eliminating two options and guessing between the last two. It scores the same as knowing the answer. It won't hold up when the real exam asks about the same idea from a different angle.

5. Untimed practice isn't the exam. Scores from short, untimed sets in a quiet room tend to drop under full length, timing and fatigue.

A better readiness check

Instead of asking "is my number high enough?", check these five things. You want most of them to be true.

Fresh questions. Your recent scores come from questions you haven't seen before: a new mock, a fresh section of the bank, or questions newly written from your material. Set aside at least one or two full mocks you never open until the last couple of weeks, so you have a clean measurement.

No weak domain left. Break your results down by topic. Look for any area well below your average, especially one with a big share of the exam. Raising a 45% topic to 65% usually adds more than pushing a strong topic from 85% to 90%.

You can explain the right answer. Take ten questions you got right and, before looking at the explanation, say why the correct answer is correct and why each wrong option is wrong. If you can only do the first half, some of those right answers are lucky.

It holds up days later. The topics you count as solid are ones you got right again days after studying them, not just in the same session. A topic you fixed yesterday is still being fixed.

Full length, timed. At least one full-length mock under real timing, ideally in the same time of day as the real exam, with a score in the range you're aiming for.

If most of these are true and your fresh-question scores are steady rather than lucky spikes, you're in a much better position than a single average can show. If they aren't, you now know exactly which one to work on, which is more useful than "study more".

When scores said pass and the exam said fail

This happens, and retakers' threads usually share a few patterns:

  • They'd done the question bank multiple times and the final scores were mostly repeats.
  • They read the explanations for questions they got wrong, but skipped them for questions they got right — including the lucky ones.
  • One topic was quietly weak and the overall average covered for it.

The fix for the next attempt is not just "more questions". It's fresh questions, explaining your right answers as well as your wrong ones, and a hard look at the weakest domain.

What about postponing?

If the check above shows a big gap two or three weeks out — a heavily weighted domain you haven't really learned, or fresh-question scores well below your target — postponing can be the honest choice. Check your exam's rules first: deferral and rescheduling policies, deadlines and fees vary by exam and change over time.

If you're close, the last weeks are better spent on review and mocks than on new material. Lifting weak topics you nearly know is more reliable than cramming ones you've never studied.

How Tali thinks about "ready"

We built Tali's readiness view around the same idea: a topic only counts as verified after you answer it correctly twice, asked two different ways, so repeating a question you remember doesn't inflate it. Topics you got right once and then missed on a new question get their own list, because those are exactly the ones a single percentage hides.
