To maximize the benefits of using past papers, students should: " outline the variables
Before diving into past papers, you must understand what you are up against. The SBO consists of two rigorous rounds. Theory Round (December)
If a question asks you to "design an experiment," outline the variables, control group, and expected data clearly. Conclusion
