Understand errors: Know the difference between systematic and random errors, and how to calculate percentage uncertainty for a burette or a pipette. 5. Organic Chemistry: The Roadmap Method
You should not start past papers a month before the exam; you should start them the moment you finish a chapter.
Edexcel examiners look for specific "keywords" in long-answer questions. For example, when discussing London forces, you must mention "instantaneous dipole" and "induced dipole" to get full marks. Read the examiner’s report
The Marking Scheme Study. Read the examiner’s report. It often says things like, "Many candidates failed to mention the state symbols, losing the mark." Don't be that candidate. 7. Resources for the "Cracked" Student Save My Exams: Excellent for concise notes.
