How do you find out the true value of a set of results in Biolgy

Answers
True value is the accurate value that would be found if a variable could be measured without error. A control in an experiment would help to provide a true value. Accuracy of an experiment is when the obtained results are closest to the true value. For example, a measured results is considered accurate if it is considered to be close to the true value. Repeating the experiment will help to judge this level of accuracy and degree of error.

What Exam Skills are Required to Pass AQA Biology?

We all know that a well designed and rigorous revision schedule is necessary to pass any exam. Make sure to use plenty of past papers and understand the types of questions that are likely to come up. This will put you at ease and reassure you that you can answer the exam. Once you're in the exam however, there are plenty of tips we can offer you to help improve and optimise your answers and exam performance. During the exam:

  1. Read through the exam! Prioritise the questions that you know the answers to easily and focus on getting those answers down. This will put you at ease. Then move on to focus on the more difficult questions, paying attention to how many marks each is worth.
  2. Manage your time. Use the number of marks per question to allocate your time. If you have a 1-hour exam and 60 marks, then spend no more than about a minute per mark. Specifically for AQA, they tend to put simpler questions at the start of a paper and harder questions at the end.
  3. Answer the question. Read through the question carefully and make sure you know what it is actually asking for.
  4. Be clear and concise. Make sure to put down only relevant information. Don't hesitate to plan your answer if it needs to be a bit longer. Make sure your sentences are short and precise and clearly answer the question. If you are asked to show your working, do so clearly, making use of the available space to answer the question.
  5. Cross out mistakes. Don't lose silly marks by leaving incorrect information on the page. Make sure it's cleary crossed out.
  6. Stay relaxed! If you're getting annoyed, pause and collect yourself and move on to a question you can answer.
  7. Re-read your work. If you have time, make sure to re-read what you've done.
  8. Keywords. Especially in biology you are going to be using a number of unfamiliar words. It is a good idea to know how to spell them and which subjects they relate to.
