    Hey, I have a question, If the question is asking for rates, its it always something divided by dt? For example dV/dt
    Unless it's stated in the question that, for example time is s, then you could use dV/dt for time yes

    What do you people do when you get stuck in an exam? As today i ended up just panicking and skipping the questions and only got around 50/75 even though in every past paper at home had been getting 70 +. For some reason as soon as i get stuck i just worry and do stupid things. How long do you spend on questions when you're stuck before moving on? As i think i tend to give up too quickly. Obviously the a star is gone which i needed for my university offer but hopefully i can salvage an a.
    I have the same problem! When I got to question 8a it stressed me out as I couldn't prove what it wanted me to.. so I rushed through question 9 to have time at the end to go back to 8 and used the product rule by mistake instead of the quotient! So just by being stressed and rushing I lost the last 5 marks on that question! On top of that when I went back at the end, I still couldn't do 8a and the stress made me make a silly mistake on 8b!

    In hindsight, I wish I had just accepted lost marks on q8 and moved onto 9 and done it properly because instead of losing 9 marks only for question 8, I've lost 9+5 marks for questions 8 and 9! Not to mention the other marks dropped in the paper

    I don't know how to stop this happening in C4??

    For me, whenever i get stuck, I circle the question and move straight on and come back to it, or I circle any question I don't think I will immediately be able to do which ensures you get all the ones you can do done straight away so you deffo get those marks then come back to the ones you struggle on when you've done all the 'easy' ones
