This assignment contains a selection of STEP 1 and STEP 2 Mechanics questions, each one with a preparation question beforehand. All of these questions contain content from the 2019 STEP 1 specification, but the STEP 2 questions are supposed to be slightly harder. There is also a solutions document to help you evaluate your work.
STEP questions are difficult, they are supposed to be and you should expect to get stuck. However, as you tackle more and more STEP questions you will develop a range of problem solving skills (and spend less time "being stuck").
NRICH Advanced Problem Solving Module 14 provides some extra practice in solving Mechanics questions.
