    For the people whom took the test, I made one cuz I couldn't find it. I felt paper was quite easy going till question 7 but the last question (question 8) which was a integration really blew my mind.
    There weren't question 9 right? I can't remember.....

    Yep, I'd say the exam was pretty easy as well. About the last question reduction formulae, you just had to do a simple splitting and do parts by integration once, then split (x^2 + k^2) ^1/2. I think there was a similar question in a GCE AL paper.

    What're your expected grade boundaries for A*?

    I will say 67~68 last integration nearly killed me. Luckily I solved in last minute. But everyone there weren't question 9 right?I am bit worried

    Anyone remember the equation of the plane in the matrix transformation?

    Do you remember the equation of the plane in the inverse matrix question? What was the angle between OA and the line L?

    was it something like 54.6 or 56.4?

    I remember it was something like that (I think 55?) so yeah probably right. Do you rememeber the equation of the plane, I found 3 points on the the plane then I found 2 vectors and then I used the cross product to determine the equation of the plane, I got something like 11x+something something=8, what did you get? Someone said I could have just mutliplied the normal of the second plane by the inverse matrix to get the normal of the first plane but I am not convinced because I am pretty sure matrix transformations do not necessarily keep angles the same.

    I can’t remember the exact answer I got but I multiplied the normal by the inverse matrix

    Wait is this a correct method?

    No cause it contradicts the definition of linear transformation

    Ahh, thankfully I did not do that, do you remember your plane's equation? Anyways enjoy summer, I think I saw you on the STEP thread.
