Well at AS last year i got a D in my empa and still managed to get an A overall in physics overall (cus i got 106 UMS in both written UMS). But now im screwed because we had our A2 empa and even though i worked towards it im pretty sure i didnt do well. Plus i need an A* in physics to get into my uni so...now im fu**ed. But enough about my life story good luck for your EMPA
