i just like to say this really helped me when i did my GCSE i got the grades i needed and well now im doing my A levels and inshallah allah i remeber these (i recodmend this to everyone espeacially the bit about praying 2 rakat before and after the priori exams, 2 rakat before the exams helps releives stress and the 2 rakat after the exams helps to remove those doubts whether you did something wrong or not, personally this happend to me and inshallah everyone does this during their exam period)
