You scores, by the way, are great. You should do well on the exam, after learning more about what to expect and learning some test taking strategies. But I would like to give you a word of caution. The required scores are high, and the exam expensive. You only get 3 times to take the CELBAN, which is much easier than the Academic IELTS. And your exam will expire in 2 years. the process to become a nurse often takes longer than that. (For example it can take 6 months to a year for all your documents to arrive at the office of the provincial college of nurses.) Also, if you fail an exam, there is a wait of 6 months before you can take it again. Furthermore, the level of stress people take when taking the test the third time is huge: their whole life and career is in the balance. That kind of stress and fear can negatively impact performance and foster procrastination.
It is important to ensure that you are confident that you will do well on the exam, and taking it in haste without preparation could be short sighted.
It will be important for you to be able to tap into your energy and excitement by writing in your journal, or creating a piece of art, that represents your emotions.
Collect quotes, or create a collage. Put it in a place when you will see it often. The darkness of winter comes, sometimes to the heart, and rays of sunshine and hope like this become so important to our emotional and spiritual well being.
