Predicted Papers vs Marked Mock Exams: What Actually Moves Your Grade
Predicted papers are useful practice. Marked mock exams tell you what you can actually score under timed conditions — and why. Here is how the two differ, and how to combine them into a feedback loop before the November 2026 IB exams.
Every IB student in the final stretch reaches for practice papers. But "doing more papers" only improves your grade if you know what your mistakes mean. That is the real difference between predicted papers and a marked mock exam: one gives you reps, the other gives you a diagnosis.
What predicted papers are — and are not
Predicted papers are original practice papers written in exam style, usually informed by paper-pattern analysis of what tends to be tested. They are excellent for exposure: fresh questions, exam-style phrasing, and a markscheme to check yourself against. Our predicted papers viewer offers free sets so you can see the format.
What they are not: a measurement of how you perform under real timing, or an explanation of why you dropped marks. When you self-mark, you tend to be generous, you cannot see your own blind spots, and you miss the method-mark nuances an examiner would apply.
Predicted papers answer: "What might the exam look like?" Marked mocks answer: "What will I actually score, and exactly what do I fix first?"
What a marked mock exam adds
A marked mock is a timed sitting followed by human marking against markscheme conventions. The output is not a number — it is a report. A good score report tells you:
- Topic-by-topic strength — which topics are secure and which are quietly costing you.
- Method vs accuracy — whether you lose marks on setup, working, or final answers.
- Timing — whether your pace holds up over a full paper.
- Careless-error patterns — the repeat mistakes that sit right on a grade boundary.
- Markscheme language — in essay-style and explanation questions, whether your wording actually earns the marks.
That is why we designed the Nov 2026 Final Mock Series around marking and reporting rather than just handing over papers — and made it open to non-Photon students.
The feedback loop that actually raises grades
The students who improve fastest in the final months are not doing more papers — they are running a tighter loop:
- Diagnose. Sit a timed mock (or the free diagnostic) to find your real starting point.
- Target. Use the score report to pick the two or three highest-value fixes — not everything at once.
- Practise. Drill those specific weaknesses using predicted papers, cheatsheets and topic practice.
- Re-test. Sit another timed paper and confirm the fix held under pressure.
Predicted papers power steps 3 and 4. Marked mocks power steps 1 and 2. You need both — but the diagnosis has to come first, or you are revising in the dark.
When to use each before November 2026
A simple rule of thumb for the run-up to the November 2026 exams:
- Now – September: one marked mock or diagnostic to set your baseline, then predicted papers to close the gaps it reveals.
- September – October: alternate — marked full papers for feedback, predicted papers for volume between them.
- Final fortnight: mostly timed self-practice on predicted papers, guided by the weak points your last marked mock identified.
Bottom line
- Predicted papers give you reps and exposure to exam-style questions.
- Marked mocks give you a score, a reason, and a prioritised fix list.
- Diagnose first, then drill — not the other way round.
- Start with a free diagnostic to find your real baseline.
Whether you take Math, Physics, or both, the principle is the same: don't just practise — measure, then target. If you want to see how paper patterns feed into practice, start with our IB paper analysis, then turn that analysis into a scored mock.

Frequently asked questions
What is the difference between predicted papers and mock exams?
Predicted papers are original practice papers in exam style with a markscheme to self-check. Marked mock exams add a timed sitting plus human marking and a score report that tells you what you scored and why — topic gaps, method marks, timing and careless errors.
Are predicted papers useful for the IB?
Yes — they are excellent for exposure and volume, especially for practising exam-style phrasing and timing. They are most powerful when paired with at least one marked mock so you know which weaknesses to target.
Do I need to be enrolled in tuition to sit a marked mock?
No. Photon's Nov 2026 Final Mock Series is open to non-Photon students. You can sit timed papers and receive marked feedback without joining weekly tuition.
How many marked mocks should I sit before November 2026?
There is no fixed number, but a common pattern is one diagnostic to set a baseline, then a full marked paper roughly every few weeks through September and October, with predicted-paper practice in between.
