      This is definitely something to ask your teachers!

      You see, it will depend on what subjects you’ve been covering and whether this is for physics or chemistry or mathematics or what. Some schools teach things in slightly different orders, so unless we ask the teachers, we don’t really know what topics you’ve covered this year.

      I didn’t go to school in the UK so I don’t know exactly, but probably if you have been taught it, it is important to learn..

      Ok I really don’t know what equations you learn in Year 9 because I am from Scotland and we have a different cirriculum, so you should definately check your notes!

      But one thing I do remember is that writing formulae is easy marks, so don’t screw them up! Like when they say “Magnesium Chloride – what’s the formula?” MgCl2 right? Sodium Chloride – NaCl etc.

      Oh and do you have to do balacing equations in Year 9? Because that always comes up in exams and you need to know how to do it because it gets important later in chemistry. So if you covered it in class, it’s definately worth revising it.

      Good luck 🙂 🙂 🙂

      Not an easy one this. As others have said, it depends on what you have to study, chemistry, physics, maths?

      All I know is that if H2O is water and CoCl2 is cobalt chloride whats CoCoA?

      I’m not sure of what you should know in Year 9, but how about Newton’s Laws of Motion (physics), how to solve a quadratic equation (mathematics), neutralisation reactions (chemistry) and photosynthesis (biology).

      Question for you: what is your favourite part of science?
