Primary General Studies, Media and Information Literacy, Paper 3: ad labelling, algorithms and account safety
Ten items on ad labelling, screen time percentages, password combinations, prize scams, echo chambers, verifying images and screenshots, three checks and immediate steps when an account is taken over.
Focus Ads and sponsored posts must be labelled; screen time multiplies seven days then divides by 168 hours; a six-digit numeric password gives 10 to the 6th power combinations; a prize demanding a fee first is a scam; algorithms that only repeat one view create an echo chamber; images can be edited or AI-generated and screenshots altered, so find the original; verify the source, the date and other outlets; change the password and enable two-factor authentication at once.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | They should be clearly marked as an ad so viewers know it is promotional. | Hiding the promotional nature misleads viewers and may break the rules. |
| 2 | 3 × 7 = 21 hours, about 12.5% of 168 hours. | Multiply by seven days, then divide by the hours in a week. |
| 3 | 10 to the power of 6, that is 1,000,000 combinations. | More digits mean more combinations, but avoid guessable numbers such as birthdays. |
| 4 | Do not pay. This is a common scam, so tell a family member or the police. | A genuine prize never requires an upfront payment. |
| 5 | People only see one viewpoint, forming an echo chamber and missing other angles. | Searching different sources deliberately breaks the echo chamber. |
| 6 | No. Images can be edited or AI-generated, so verify the source first. | Images stir emotions more than text, so they need more checking. |
| 7 | Find the original video or report, because screenshots are easy to alter. | A screenshot loses its context and is easily distorted. |
| 8 | Whether the source is reliable, whether the date is current, and whether other trustworthy outlets report it. | Recycled old news is common, and checking the date saves time. |
| 9 | Change the password at once and turn on two-factor authentication. | Also warn your friends so the scammer cannot use your name on them. |
| 10 | No. Birthdays are easy to find on social media, so use a long mixed password instead. | Personal details are widely visible online and are not secrets. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
