What you face with the old way
- ⚠ Paper-based practice: You finish and check answers yourself, never knowing why you got it wrong
- ⚠ Scattered revision: Without knowing your weak spots, you study everything and waste time
- ⚠ Outdated papers: Last year’s exams, not aligned to the newest structure
- ⚠ No essay grading: Written answers go unread, so you never know your real score
Tips to practice effectively
1. Simulate the real thing
Time yourself exactly, no looking things up, to see your true level.
2. Read the AI feedback
Do not just look at the score — read what the AI flags to spot the question types you miss.
3. Target your weak points
Take a few exams, check the per-subject breakdown, then focus on your weakest subject.
