    As I wrote lots of different marks to get the marks in some questions, some of my answers were not written on the dotted lines coz i didnt have enough space.
    Will the answers which are not on the dotted line be still marked ?
    That prob depends on the examiner. I'm sure if they're easy to spot as an they'll get marked

    Thanks
    I hope they see it
    its not hard to spot. its just right beneath the lines. literally right beneath the lines.

    For the question about Coil P and Coil Q, I put no current in the Ammeter to begin with as the current in Coil P was D.C. And then 2nd part) a sudden change in resistance leads to a change in current which is a change in the magnetic flux cutting Coil Q so since there's a change , there's a reading any idea if that's ok?

    There was a similar emf question on a 2005 paper, in the exam I remember seeing "average emf"
    No RMS or other equations

    Not too bad to be honest. It was a fair paper, I just made a few silly errors. Only thing that angers me is the typo.

    Right ss, just wondering if i got any marks, on the coil question, I wrote about how when the circuit is closed a magenetic fiield is produced which exerts a force on the other coil so to equal the force F=BIL shows us a current must occur to enduce an opposie force.

    I then said with a higher resistence there will be a lower current so there will be less force so a lower ammeter reading on the second one.

    ANY MARKS / 5 ?

    Examiners are not robots. If they can clearly see you attempted to answer a question somewhere on the page and it isn't ambiguous, they'll include it in marking it. I barely ever get through an exam without going over the dotted lines given.

    Probably 1 or 2 (if lucky)/5
    Didnt say induced emf or directions

    I would pretty much 95% of people who took this exam would have only got 1-3 marks for this question and the dampening question, they were both extremely demanding. Hopefully the grade boundaries will be similar to last year

    All of the calculation questions were nice, but I messed up the dampening question (made the seemingly constant error of saying how m is independant of T) and yeah the coil one was not nice at all...

    i am so pissed i for some reason read the question about the horizontal! circle to be a vertical circle so thats at least 18 marks down the sh*tter. I don't know i don't think physics is that bad i just keep making these kind of stupid mistakes. Goodbye A/A*

    Can i still do well if the unit 5 goes well?

    What did people get for the cars collision where it asked the new speeds? 14? Times by root 2 or something
    Also the planet gravitational force when radius waa doubled and density halved?
    Rather annoyingly i couldn't show the charge of the electric field in 2 to be x10-9
    kept getting 13 and 14
