*DISCLAIMER* This is not intended to be boastful at all.
I got 8 9s, 1 8 and an A* in EPQ which I took 2 years early. My 8 is currently getting remarked because it was in english lit, and I got 100% on paper 1, yet was torpedoed by the examiner in paper 2 who gave me 67/96.
I will admit I didn't take the most conventional subjects:
Art-9
Drama- 9
Eng lang- 9
Eng lit- 8
Physics-9
Maths-9
Russian-9
Spanish-9
History-9
EPQ-A*
There are certainly methods to how I got these grades and I am perfectly willing to share if anyone is interested.
