IGCSE Grade 11 and Grade 12 Chemistry Study Tips

  • Read through all the explanations in books. Fully understand each page, before moving to the next.
  • Actively participate in all experiments. These will help you to improve practical skills for Paper 3 and 5.
  • Do not memorise the notes without understanding them.
  • For concepts which you can’t understand just memorise them
  • For calculation based concepts, you need to know to apply them in relevant questions.
  • Regularly revise each topic again. By revising again and again, concepts become clear.
  • Once you are through with the topics, solve all the past year question papers keeping in mind time limit.
  • Understand the marking schemes. In Chemistry, most marks are independent of any other marks. This means that you can score marks without other marks also being scored.
  • In marking scheme, if any Chemistry term is underlined or highlighted, you need to use the same term in the answer. No other term is acceptable even if the meaning is the same.
  • In marking scheme, if any non-Chemistry term is underlined or highlighted, you need to use the exact term or other terms with the same meaning in the answer.
  • In marking scheme, if any words are placed in brackets, then you don’t need to use those words in the answer.
  • When doing revision before exam, you should first go through the topics and subtopics, that you have not studied for long time.
  • For Chemistry Paper 3 and Paper 5, you should check the past year questions and the mark schemes. The question pattern is almost same every year. You need to remember the answers of frequently asked questions.

Chemistry Paper 1

  • You need to read the questions and options carefully. Do rough work on the question paper only. Use process of elimination to find the correct answer.

Chemistry Paper 2 and Paper 4

  • Read the instructions and questions carefully. Make sure you know real meaning of the question ie what is being asked. Some questions will test you on more than one topic. You may also be asked to give your opinion in some questions.
  • You can use the same or similar words or sentences as given in textbooks. Make sure that the answer suits the question. If the question is out of the textbook, then answer it in your own words. Keep your answer specific rather than too general.
  • Use the correct Chemistry terms in answer. Do not replace them with terms from other subjects. If you spell non-Chemistry term wrongly, marks will not be deducted. Same is not true for Chemistry term. Do not use short forms too often.
  • When answering numerical questions, you should show all calculations. Do not skip the important steps. The unit for the final answer should be correct. Write down the formula used to solve the question.
  • Write your answer to three places from decimal. Do not write answer in fraction or surd.
  • If question that requires explanation, give proper detailed answer. Answer in complete sentences, rather than short forms. The number of marks allocated for the question will give you how much effort you need to put. Marks are only given for the correct points. If your points are irrelevant, but not wrong facts, no mark will be deducted.
  • When drawing diagrams, make sure to show important details and label all parts in the diagram.

Chemistry Paper 3 and 5

  • Make sure that you have understood the experiment given, only then start the work. Certain question may require you to record the readings. Draw the tables starting the experiment.
  • Some questions will require you to put your Chemistry knowledge and understanding. In these questions, you will be asked to give your own opinions. Keep your answer too them point, not too general.
  • While recording readings, the number of decimal places used should be equal to half of the smallest division of scale of the instrument. For digital instruments, the number of decimal places should be same as displayed.
  • For titration questions, first perform a rough titration, then two accurate titrations.
  • When plotting graph, draw both horizontal and vertical axis on the graph paper properly, units and label both axis.
  • For qualitative analysis questions, use about 1 cm depth or 2 cm3 of each solution unless stated otherwise. Record all the observations. State if any colour changed or if precipitate formed. For any colour change, you need to indicate both the initial and final colours.
  • For questions involving calculation, you should show all workings and not skip any important steps. Needless to say, write the correct unit for the final answer, if it is not provided. Do not write extra solutions or answers.
  • When drawing diagrams, show all important details along with labels. Draw clear and neat diagram.
