    The highest an A* has ever been for astro was 62/75; that paper was June 2011 and was ridiculously easy- it's not going to be higher than 60 for an A*.

    **** this. Not checking any comments or mark schemes to get my self depressed over the summer

    The paper was ok. Section A was straight forward APART FROM THE ****ING 6 MARKER

    Section B was Hard (turning points) but the 6 marker was just bliss!!!

    Do you think I'll get the mark for putting alpha is 0.05m and beta 0.1? (I've seen the alpha range to be 5cm on other papers)

    Then you would need to add two AU (one for each side of the sun for the whole diameter of earths orbit)

    Easy 6 markers dont make up for calculations . Some calculations in turning points were kinda tricky.
