I need help with igcse chemistry and biology revision?!?!?!Watch
Any help is appreciated.
Definitely do lost of past paper questions then mark them yourself and look at which questions you keep getting wrong so you know where to focus your revision. It also means when you go into the exam you will be more confident answering questions. Physics and Maths Tutor is a great website that should have lots of resources for your courses. You need to find the best way for you to remember things. For me, if I need to memorise a process I'll draw a picture every time I go through it. I have a visual memory so in an exam I can start to draw the picture and it will trigger my memory of the information to go with it. It might take a while to find what works for you but just keep trying. Try to vary the way you revise because it does get boring so do a mixture of flash cards, mind maps etc. Making notes now will definitely benefit you when you come to needing to start learning the information but you do have a long time until January so don't panic yet about them! Just put aside time to go over things and gradually build up the amount that you do as you get closer to the exams and definitely ask for help when you're stuck
^^ That's great advice. I second all of that!
Actually, if you read science blogs, that's exactly what they suggest: mix techniques, practice questions, visual memory. (e.g. http://www.learningscientists.org/bl...y=For+Students)
You should definitely do your coursework, but could also do revision, maybe 30-60 minutes a day, every 2 days, or so? I think Seneca would be perfect for that, because it covers all content and the sessions are only 10-minutes long, so you can fit them in your schedule quite easily! And there are courses for CIE IGCSE and Edexcel IGCSE (you didn't mention which one you're doing, but they have both anyway!) - www.senecalearning.com - You have to create an account, but it's all free, so don't worry.
FOR chemistry , memorise the colours ,the test for gases,the test for ions,the conditions,know how to do the calculations since that is worth a lot of marks in the exam.Learn the conditons in haber process,learn the eqautions in the blast furnace.Learn the flame test,test for sulphides,chlorides,and bromides,learn the test for unsaturation.learn the reactivity series and also properties of group 1, 7 and noble gases.MOst important is organic chemistry.KNow the properties of a homologous series,addition reactions,subsitution reactions,making ethanol from hydration and fermentation and its adv and disadv.KNow the properties of crude oil,fractional dstillation and the uses of the fractions and also know cracking and its conditions.learn the displayed formulas and repeated formulas for polychloroethane,polypropene,etc Learn esters and nylon.MOST IMPORTANT learn the giant structures and rate of reactionsALSO KNOW MAKING SALTS USING TITRATION AND PRECIPITATION.FACTINAL DISTILLATION,CHROMATOGRAPHY
MOst IMPORTANT CHAPTERS IN CHEMISTRY

also make notes out of the markschemes.
PLEASE PRAY FOR ME INSHAALLAH ILL GET A*s.IT literally took me an hour writing this and i hope u do well in ur exam.Good luck
