ITGS practice exam questions are a good way to prepare for the (rapidly closing) final ITGS exams. We have studied lots of past papers in class, covering questions from as far back as 2012 to the most recent exam papers. (You need to be careful with older papers because the exam format has changed somewhat. However, often the individual questions are often still useful). If you have exhausted our supply of IB past exam papers, here are a few exam style questions to keep you going:
