Welcome to the online STACK questions where you can practice skills and get instant feedback. Each time you try a question it will be slightly different!

This bridging course has been designed in response to school closures due to the Covid-19 pandemic to complement efforts made by school to prepare UK students for the jump between GCSE/iGCSE and A-level. For users from outside the UK, we believe the materials can still be relevant and stimulating and would be happy to discuss how they could be adapted to serve different countries' unprecedented needs.

This course is completely free. Students who would like to participate can enrol directly and take part. Schools that would like to offer the course to their students can request varying degrees of support which we will endeavour to offer freely subject to capacity. All the materials in this course are openly available.

This course has been prepared and is run by IDEMS and SAMI as a joint effort to support learning in these difficult times. Several activities are based on fantastic resources from NRICH and other brilliant websites.
