How this technique can turn Cs into As

This study technique could be the ah ha moment your teen is looking for. For all those students that actually do put in the study hours but dont get the grades they were hoping for, making this relatively simple change in their study process should enhance their ability to convey to examiners that they understand the issue thats embedded in the question.
To get those top grades, examiners are often looking for that little bit extra that in depth understanding something that separates your teens answer from the rest of the pack.
Obviously your teen cannot predict the exact questions that are going to come up in assessment, but they should be able to making a fairly good guess at the types of questions that are likely to come up, like my mitosis/meiosis compare and contrast example.
