Things to do When Exams are Approaching

As Your Exams Approach, You Should Keep These Points in Mind -

  • Try to take care of yourself as your health is the most important, especially when the exams are approaching. Eat healthy food, get adequate sleep and stay hydrated.

  • Avoid learning any new topics and concepts when the exam is approaching, as you won’t be able to remember it properly, and you might end up forgetting what you’ve already learnt.
