Self Assessment Checklist – Atomic Structure

Knowing the learning objectives is the first step in acing Chemistry. Master the essential concepts and apply them to interesting Chemistry questions confidently. Topical syllabus objective checklists are available here for your self-assessment. These checklists are based on Cambridge O-level Syllabus. Conduct self assessment when you revise. Tick against objectives that you can confidently say ‘I Can Do It’. Revise objectives that you are unsure of. Knowing what you need to know builds confidence in tackling questions. 

Work hard. Work smart. All the best.
