      Ok for science make sure u know all the experiments including non mandatory , and write them out and make sure to know oxygen,carbon dioxide,fossil fuels as they are an guaranteed question

      ask me any questions u need and ill help

      I am very unprepared for Science, any suggestions on what could come up or suggestions on stuff that comes up regularly?

      what chapters wouldu recommend revising that ost come up on for science as i only have this evening

    10. avatar image


      tbh you gotta revise everything. Theres nothing definite that can come up

      I've honestly never gotten the static and current electricity stuff and all the light bulbs. Anyone have any useful links or description?

      THE PHYSICS TEACHERS GO ON it the best!!!! it has all the notes on what u need

    13. avatar image


      make sure to study for chemistry; oxygen,carbon dioxide,fossil fuels,titrations,water they always come up no doubt

      Charges can be positive or negative. Positive charge is a lack of electrons and negative

      charge is an excess of electrons. Like charges attract and unlike charges repel. Some of the

      atoms are charged. Proton is positively charged and the electron is negatively charged. A

      body with a charge on it is said to have static electricity. Bodies become charged by the gain

      or loss of charge. A conductor allows a charge to move e.g. metal. An insulator holds a

      charge e.g. polystyrene rod. All charge tries to go to Earth. The earth is a source and a sink

      for charge. Electric current is the movement of charge through a material. Current is

      measured in amperes or amps and has the symbol l. The size of the current can be measured

      by counting the number of electrons that pass a point in a second. Potential difference AKA

      voltage is the energy needed to pull on the electrons between any two points in a

      circuit. Potential difference is measured in volts and given the symbol V. The potential

      difference of a battery is called the electromotive force of the battery. The electric resistance

      of a material is a measure of how much energy is needed to pull charge through it. The unit

      of resistance is called the ohm and the symbol for resistance is R. Voltage is equal to

      resistance by current. Devices can be connected in series or parallel. The advantage of a

      parallel circuit is that if one bulb blows, the others continue to work. The lighting circuit in a

      house is wired in parallel.

      Thank you so much! This is an amazing help.What would you say would be the top ten most important experiments, I can't really learn all 30 in one night. I regret not doing much for science.

      I found this if it can help anyone else as well.

      The oxygen,carbon dioxide,titration,photosynthesis,germation,transpiration,heat gas expansion and contraction,sound experiment,ohm law experiment,measure resistance of ldr
