Don't know what to revise? Not enough time to revise? Let Rudi Rabbit help by asking you a whole bunch of Chemistry questions and then suggesting which topics you have done least well on. Once done, you can either choose questions at random or only on specific topics. This app is aimed at those students studying for A Levels in the United Kingdom but may also be of use to those studying the International Baccalaureate and other International examinations. The free version comes with 160 questions, but if you find it useful why not upgrade by adding over 500 extra questions by purchasing the Extra Questions Pack? If you select your examination board, Rudi will even tailor the questions to your specification.
