Start with a topic, work through an example, then try some questions on your own.
Practise one topic at a time, mix topics or try a short exam-style set. Your progress is saved separately for this course.
If you get stuck, choose prepared guidance or optional AI Tutor for a conversation about this course. Recovery helps you revisit a topic with support before trying fresh questions on your own. Tutor Scotland checks ordinary science practice within the site. How optional AI Tutor uses information.
Use the feedback to decide what to practise next. If we can’t check an answer reliably, we’ll show it as unconfirmed. Practice feedback does not give official marks or predict a grade.
Use original practice investigations and sample data to prepare for your assignment. Do your assessed assignment yourself and follow your teacher’s guidance. You’ll need supervised practical work to show your lab skills.
