I did worse in my second set of mocks a levels...

In yr12 i got pretty bad mock grades (CCE) maths psych and E in bio and i had a pretty rough time telling my parents... they gave me another chance but I messed up my feb yr13 mocks and got 2Es in bio and maths (i havent gotten my psych, but im feeling pretty confident maybe a B?) and idk what to do ☹️

For context- im really not that dumb in school ive gotten As and Bs in both maths and bio but its always mocks where i get the lowest grade and exams are only 2/3 months away and im stressing. Is it possible to bring my two Es to 2 Bs in my real exam? Also does anyone know how to approach VERY strict parents about doing worse after they gave me a second chance? Please let me know!! -also kindly asking for some motivation 🙂
