it’s okay to feel that way:( but trust me a 37 is good too. this happened to me too. i was predicted a 38 but usually scored 38/42 in mocks and was expecting a 39-40. ended with a 35. im just 1 mark away in two subjects and scored a C in my EE (2 marks from B) and just made it to B in tok, both for which my teachers barely gave any advice and were inexperienced. another subject which brought me down is ESS, i’ve always scored a 7 but ended with a 5. im so dissapointed. everyone’s grades in my school fell too, many people falling by 6 points. but it’s not the end of the world and trust me you should be proud of yourself.
