How should I revise if I don’t know where to start?
Start with a 15-minute PrepLab session in your weakest subject. After a few sessions PrepLab builds your personal mistake list, so every session after that tells you exactly which topics to revise next — no study timetable guesswork.
Do my parents need to sign up too?
No. You can sign up and practise independently. If your parents want to track your progress, they can link a parent account later using a code you generate.
How is this different from just doing Ten Year Series?
TYS gives you questions. PrepLab tells you which questions you personally need most — because it tracks your mistakes and builds a picture of your weak spots over time. It gets more useful the more you use it.
