All preregistration trainee pharmacists are required to pass a 40-question calculations assessment in two hours. This can be quite daunting especially if you are not prepared.
Here are my top tips to help you both before and during the assessment. A lot of additional, useful information can be found in Section 5 of the GPhC preregistration manual.
How to prepare before the assessment
Below are tips on how to prepare for the calculations paper. Ideally, preparation should begin at least three months prior to the assessment.
12 weeks before
- See GPhC learning points from June and September 2016, 2017 and 2018;
- Download a copy of the answer sheet and front page of paper one from the GPhC website;
- Download the GPhC calculations framework.
8 weeks before
- Ensure that you have attempted the 12 GPhC sample questions and understand how to answer them;
- Watch the six GPhC preregistration videos.
4 weeks before
- Ensure you are clear on how to complete the calculations answer sheet. Review this on the GPhC website and with your tutor if unclear;
- Make sure you fully understand what is, and is not, likely to be asked. Concentrated waters have been removed from the framework;
- The phrase “Round to the whole number unless otherwise instructed” has been removed from the answer sheet and front of paper one. If a question requires rounding then the question will specify this;
- Understand that you have three minutes per question which includes time to answer the question, check your answer and transfer it to the answer sheet;
- Take care when revising from old mock questions. These are not official. These are not past papers. There may be errors;
- Make sure that you fully understand how to round to one decimal place, two decimal places, nearest whole number, nearest 5, nearest 0.05, nearest tenth, nearest hundredth etc. You could also be asked to round up or down;
- Acquire a GPhC approved calculator.
What to do in the assessment
- As soon as the assessment begins, write down anything you are worried about forgetting, no matter how trivial. For example, formulae and definitions;
- Round as per the instructions on the question;
- If you do not like the look of a question, do not panic. Leave it, highlight it and come back to it at the end;
- Do NOT spend too long on the more difficult questions and lose track of time;
- Remember each question is worth one mark;
- Transfer your answers as you go along. Do not wait until the end;
- Look at the units on the calculations answer sheet before attempting to answer the question so you know what you are trying to work out;
- Make sure your final answer is stated in the required units and you do not use microgram/minute instead of micrograms/kg/minute;
- Read each question at least twice and underline important points — no matter how easy the question looks;
- Highlight the end of the question so that you have identified any rounding instructions. Highlight all the numbers in the question and then ascertain if you need to use them all;
- Do not leave the assessment early. In the unlikely situation that you have time to spare, triple check your answers. Do not discuss paper one in between papers on the day and definitely not after.
Tips for specific calculations
- Round up with Number Needed to Treat and down with Number Needed to Harm;
- Round at the end of the calculation unless working out a dose;
- Does your answer make sense? Are you really going to give 27 tablets per single dose to a patient? If you are diluting a 10% solution, then the final concentration MUST be less than 10%.
It is important to remember that most candidates pass the calculations paper. You have already undertaken many calculations at university involving the same topics. GPhC questions may contain more words than university questions. Please do access the Pharmacist Support website if you are feeling the pressure.
This is not mission impossible. It is mission slightly difficult. Good luck!
