    GCSE Science and Maths revision

    Report bad ads?



    i thought i'd make this thread as i'm hoping that it would help each and every GCSE student that is a member of this forum (and possibly even people who aren't members of this forum).

    here, you can post anything that you've learnt today...bearing in min that this is a science and maths thread ONLY...i dont want to see posts regarding the climate or the nazis. this can aso be regarded as a thread where you can ask questions that you do not know the answer to or even quiz each other.

    but...as quite a lot of threads, this thread requires you to sign a set of rules.
    • no googling the answer, copying and pasting...feel free to research the topic, make notes...and then come back to answer...that is once you know that you have learnt the topic well.
    • no off-topic posting (duh!)
    • if you are a non GCSE student willing to help us poor enslaved students, feel free to do so.
    • you can only post an answer to a question if you are a GCSE student...but anyone (even if you are not a GCSE student) can ask GCSE science or maths related questions.
    *hmm...i think there were more rules...but i've forgotten them...so that's it for now*

    this thread can also be used as an excuse as to why you are being online when you are supposed to be revising for your exams...but if the excuse doesn't work, i am not to blame...*i know, i never was a good influence on kids*

    first question (as today, i didnt learn anything in school cause i wasnt bothered)...

    1. What are the three different types of rocks? Examples for each of the types.
    2. Two types of igneous rocks and one example for each type.

    they're both two types of waves, sound travels as a longitudinal wave and the same with transverse but it has a higher amplitude and wavelength

    In a quadrilateral, I think it's length x width

    In a triangle it is (Base x Height)/2
