The Five Mistakes That Cost Edexcel Students the Most Marks

Examiner reports are public and free, and almost nobody reads them. They are the closest thing to a leaked mark scheme you will legally get.

The most common error isn't a content gap — it's answering the question the student expected rather than the one that was asked, especially in 'explain' and 'suggest' questions.

Significant figures and units cost more marks across a paper than any single content area. Build the habit early; it's free marks every single exam.
