    Amazing notes for physics paper 6!!

    guys dont ALWAYS round to 3sf , IF ITS A TABLE AND THE VALUES ARE IN 2 S.F THEN WRITE THE VALUES IN 2 SF

    check the w11_gt to know most likely boundaries , and they take what you got as a percentage in paper 3 for example as a percentage of the 50% and same for other papers . just add all the marks and divide by 160 and x100 is probably done

    i think you got the angle of incidence rong , its "sin i / sin r" and angle i was either 40 or 50 i cant remember what i wrote so sin40/sin90 or sin 50/sin 90 is the right answer im sure AND you used the formula rong angle of incidence wasnt 90

    sin of angle of i / sin of angle r which is sin 50 / sin 90 which was 0.6 sumthing

    Physics Pp:3-Variant 2- Discussing Answers!!

    no it was sin50/sin90 which gives 0.6 sumthing

    no .. refractive index was much lower and the efficiency is right i got a similar answer

    Physics Pp:3-Variant 2- Discussing Answers!!

    oh well i hope i got 2 marks for that one if your right , i think i lost all the magnetism marks (or most of them) and possible some on the electric charge and like 2 on the energy one so ye i hope its an A if boundaries are low , or B if somehow theyre high

    it goes from 51 and halves to become 26 and if u look at graph it goes 2.6 i double checked , and for the bird thing i got anticlockwise

    for 3 i got 2.6 days , you had to use the graph i think

    it wasnt harder than winter 2012 papers i think it was more clear the questions but the paper was still difficult

    What are the grade boundaries for Physics extended?

    paper 32 , it was kind of hard but i did good i guess

    What are the grade boundaries for Physics extended?

    ya finished paper 3 today
  20. K

    What are the grade boundaries for Physics extended?

    maybe like 50 for an A cause it was hard i think
