Edexcel A Level 9MA0 | Logarithms & Exponentials PYQs | Inequalities, ln Tricks & Exam Traps

Tackle the most mark‑losing Logarithm and Exponential questions from Cambridge A Level 9709 and Edexcel 9MA0 Pure Mathematics 1. This session walks through carefully selected previous‑year exam questions on inequalities, ln transformations, and multi‑exponent equations using a clear, pen‑tab, step‑by‑step approach.

This video is built for serious A Level students in the final months before the exam who have finished the logs & exponentials chapter but still drop marks on “small details” like inequality sign reversal or messy ln steps. Each question is chosen because it represents a high‑friction exam trap that examiners love and candidates consistently mishandle.

What we cover:
A Level 9709 / 9MA0 Pure Mathematics 1 previous‑year and exam‑standard questions
Exponential and logarithmic inequalities: when and why the inequality sign reverses
“Show that” questions using natural logs: clean, examiner‑friendly transformations
Transcendental and multi‑exponent equations: structuring solutions logically
Checking domains and validity of solutions (no awarding marks to invalid roots)
Clear marking‑scheme style layout: where method marks and A marks are usually given
High‑loss topics we fix:
Treating all inequalities the same and forgetting sign changes when multiplying/dividing


Who this video is for:
Edexcel 9MA0 Pure Mathematics 1 students revising 2–6 months before exams
Students who are comfortable with basic log laws but lose 3–5 marks on tricky inequalities and ln‑based proofs
Anyone building a focused exam‑prep playlist on Logarithms & Exponentials, alongside theory and “laws of logs” videos
