im in year 12 and ive recently completed my mocks (these are the first ones i've done) and we've got all of our grades back and i got a C in physics (one mark off a B), a C/D in maths (boundaries haven't been decided yet) and an E in chemistry. i just feel really disheartened by the results that i got like i put in a lot of effort for them and this is all i got. everyone keeps telling me that its fine because its my first mocks but i dont know whether to believe them or not. i think its also hard for me to see low grades because i did well at gcse and always got 8s or 9s in these 3 subjects consistently. is it normal to do badly on the first mocks? is it going to be too hard for me to get into A grades?
