These include new textbooks and authors with updated editions. This is especially common when a new curriculum has been started and implemented.
Exciting developments are also appearing on the internet. For individual subjects e.g. mathematics, both global and Scottish school curriculum websites have been built. Individual schools also provide excellent study guides and tutorial exercises for both fellow Scottish school students, and exclusively for their own students. Schools may also ask for homework to be accessed and completed online. Other countries will be similar.
Having enjoyed the privilege of providing private home tuition for many years, I am very keen to give extra choices to my parents and students, and provide an opportunity for parents who live in Scotland and further afield to have extra access to private tuition.
