This site provides maths resources for both teachers and students.
Whatever exam anyone wishes to pass, an essential help are questions that are similar to the questions in the exam. Hence these powerpoints contain exam type questions followed by a solution.
Teachers can project the question on a screen, then talk through the solution one step at a time.
Students working on their own could see a question, answer it, and then have immediate feedback (an essential in confidence building). If the question seems impossible then a simple click to see the first or second step will be invaluable.
