A personal tracker is a table with one row per syllabus topic, grouped under biology, chemistry and physics, and a status you update honestly. It turns “I have revised a lot” into “I am ready on these topics and not on those”.
It follows separating a two-grade award from two subjects and sits in the double-award scope and entry module.
What goes into the tracker?
Start from the syllabus document for your confirmed code and exam year. Copy the topic headings for each of the three sections. Then add four columns:
| Column | What you write |
|---|---|
| Status | Not started, in progress, secure |
| Last practised | The date of the last task, not the last time you read it |
| Error type | Recall, calculation, reading the question, evaluating evidence |
| Next step | One concrete task, such as a fresh question on that topic |
Mark “secure” only after you have answered a fresh question on the topic without help. The mistake log and retest queue can store the error notes and suggest when to retest.
How do you read the tracker?
Count topics by status in each section, then compare coverage across the three. A section with many “not started” rows needs hours before the others do. Use the weekly review to move one or two topics forward, not ten.
Worked example
This is an invented tracker summary for a student. The numbers are made up for practice.
| Section | Topics listed | Topics secure |
|---|---|---|
| Biology | 30 | 18 |
| Chemistry | 25 | 12 |
| Physics | 28 | 21 |
Coverage per section:
- Biology: 18 ÷ 30 = 0.60, which is 60%.
- Chemistry: 12 ÷ 25 = 0.48, which is 48%.
- Physics: 21 ÷ 28 = 0.75, which is 75%.
Overall coverage: add the secure topics and the listed topics first. Secure: 18 + 12 + 21 = 51. Listed: 30 + 25 + 28 = 83. So 51 ÷ 83 ≈ 0.614, which is 61% to the nearest whole percent.
Chemistry is the lowest at 48%, so it gets the extra hours next week.
Notice that the overall figure is not simply the average of the three percentages. (60 + 48 + 75) ÷ 3 = 61 happens to be close here, but only because the section sizes are similar. If the sizes were very different, the two answers would drift apart.
The mistake to watch for
Mistaken calculation: averaging the three percentages and calling it “overall”, for example if physics had 10 topics at 100% and biology 40 topics at 25%, giving (100 + 25) ÷ 2 = 62.5%.
The correct overall figure is the total secure ÷ total listed: (10 + 10) ÷ (10 + 40) = 20 ÷ 50 = 40%.
The correction is to weight each section by its number of topics. The check is quick: add secure topics and listed topics first, then divide once.
Check yourself
1. A section has 24 topics and 9 are secure. What percentage is secure?
Show answer
9 ÷ 24 = 0.375, so 37.5%. Check: 0.375 × 24 = 9.
2. Using the example table, which section would you give more time next week, and why?
Show answer
Chemistry, because it has the lowest coverage at 48% against 60% for biology and 75% for physics.
3. Why should “secure” require a fresh question answered without help?
Show answer
Re-reading notes feels familiar but does not show that you can recall or apply the idea. A fresh question tests the idea itself, so the status reflects what you can actually do.
Where this leads next
With a tracker in place, compare your resources against the official scope in comparing 0654 with separate-science resources. Then try the module practice set. If you want a teacher to check your tracker against the syllabus, see online one-to-one Co-ordinated Sciences tuition.
