Frequently asked questions

Where should I start?

If you are new to the course, begin with Spectroscopic Techniques. If you are revising, start with a diagnostic for the earliest weak area.

How should I repair a weak topic?

Attempt the diagnostic without notes, follow the generated repair plan, then return later for its delayed re-test.

When should I use quizzes and structured practice?

Use quizzes for retrieval and quick diagnosis. Use written practice for calculation setup, explanations, mechanisms and method marks.
