R2R: GCSE Chemistry 4+

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. If you select your examination board, Rudi will even tailor the questions to your specification.
