My oldest son did Highers in 2014 (he was last year group to do Standard Grades). My youngest (just finished his Nat 5s) will start Highers when he goes back to school after exam leave. 4 of the 5 subjects he will take were the same as my older son - does he need new Revision/study guides (Leckie and Leckie type things). Just don't know if/how Highers have changed (if at all) so don't want to waste money or be stingy. Any advice welcome
