Direct answer
Percentage change questions ask students to compare an original value with a new value, then express the difference as a percentage of the original. StudyVector helps by turning sign errors, wrong denominators and multiplier mistakes into short repair practice.
Find the change, divide by the original value and multiply by 100. For reverse percentage, work backwards from the multiplier rather than guessing the starting value.
Students often divide by the new value, forget the direction of change or mix percentage points with percentage change. Those mistakes should go into the Error Log.

| Option | Best for | Limit to watch |
|---|---|---|
| Generic AI chatbot | Explaining a broad idea or rephrasing a concept. | Usually does not know your exact board, live coverage, weak topics or saved mistakes. |
| Flashcard app | Fast recall of definitions, formulas and facts. | Recall alone does not show whether a student can earn marks in an exam answer. |
| Revision website | Reading notes and checking a topic explanation. | Many pages stop before the practice, feedback and retry loop. |
| Past-paper site | Seeing official question style and mark schemes. | Students still need a way to turn mistakes into topic-level repair tasks. |
