Method over memorisation is the one thing that matters most
Most students who struggle with IGCSE Add Maths don't lack effort — they've learned to copy worked examples without understanding the method underneath. It works until the exam rephrases the question. When you talk to a prospective tutor, ask how they teach a hard topic. If the answer is "lots of past papers," that's drilling. If it's "we make sure the student can explain why each step works, then practise," that's method-first teaching — and it's what transfers to exam-style questions.
