This is the official Edexcel mark scheme for Geography Mark Scheme Unit 4 from the January 2023 session.

This mark scheme corresponds to January-2023-QP---Unit-4-Edexcel-Geography-IAL. For maximum revision benefit, attempt the question paper under strict exam conditions first, then use this mark scheme to self-assess. Pay attention to the marking notation: "allow" means an alternative is accepted, "do not credit" means a specific phrasing is rejected even if technically correct, and "ORA" (or reverse argument) means the mark can also be earned with the opposite reasoning.

Edexcel mark schemes reward precise language. For Geography, look for keywords the examiner requires — definitions must include specific terms (e.g., "per unit mass," "resultant"), and calculations must show working even if the final answer is correct. Understanding mark scheme conventions helps you write answers that hit every marking point, not just the general idea.
