MARK SCHEME[3 marks]
Q3 Find ∫01 x ex dx
= [x ex]01 − ∫01 ex dxM1
= e − (e − 1)A1
= 1A1
Every practice set comes with a full mark scheme. M marks reward a correct method, A marks a correct answer that follows from it, and B marks stand alone. Students see exactly where each mark comes from.

About

Hello from Sincere Math Studio

I teach mathematics for international and Singapore curricula, from O-Level up to A-Level Further Mathematics and IB Analysis & Approaches HL.

Lessons follow the exam. For each topic we build the ideas first, then work through recent past-paper questions chapter by chapter, and finally mark them against the official scheme so students know which line lost the mark and why.

  • LevelsO-Level, A-Level, IAL, IB Diploma
  • Lesson formatOne-to-one or small groups of 2–4, online or in person
  • LanguageEnglish, with Mandarin explanations when helpful
  • MaterialsOriginal notes, summaries and topic practice sets with mark schemes

How lessons work

  1. 01

    Free trial and diagnosis

    The first lesson is free. We work through a short set of past-paper questions so I can see where your child is losing marks.

  2. 02

    A plan back from the exam date

    We fix the target exam series, then plan each chapter against the weeks left, with full timed papers before the exam.

  3. 03

    Feedback after every lesson

    You get a short written note after each lesson, and every practice set is tracked so you always know where things stand.
