DS is waiting to see if he has an offer from Cambridge to study maths at the end of the month. Also applied for Warwick so at some point will need to take the STEP exam. His state school have suggested he do a course provided by the above company in preparation. He doesn’t know much about it apart from it possibly being some form of online tuition/coaching. We’ve been sent a random £160 invoice for this course from school with no explanation. Before I contact school in the morning for more details I just wondered if anyone had heard of it and if it was worthwhile. DS has been tackling questions alone since the Summer and has found a fair amount of advice online about the exam but this has confused things a bit and we’re wondering if it’s vital. Thanks in advance !
