The Computer-Based Test (CBT) is the first practical hurdle in the NMC registration process for internationally trained nurses. It tests your theoretical nursing knowledge against UK clinical standards and must be passed before you can proceed to the OSCE. The good news is that the CBT can be taken in your home country, and with focused preparation, most nurses pass within one or two attempts.
What Is the NMC CBT?
The CBT is Part 1 of the NMC Test of Competence (ToC). It is a computer-based, multiple-choice exam administered at Pearson VUE test centres worldwide, including several locations across India. The test assesses whether your theoretical knowledge meets the standards required for safe nursing practice in the UK.
The exam has 115 questions and takes up to four hours to complete. It is divided into two parts that are taken in a single sitting.
Exam Structure
Part A: Numeracy
Part A contains 15 drug calculation questions. You need to answer at least 14 correctly (approximately 90% accuracy) to pass this section. Questions cover dosage calculations, fluid balance, IV drip rates, unit conversions, and medication administration based on patient weight. This section is pass/fail — there is no partial credit. If you fail Part A, you fail the entire CBT regardless of how well you perform on Part B.
You are not allowed to use a calculator. All calculations must be done manually, so you need to be confident with mental arithmetic, fractions, decimals, and basic algebra.
Part B: Clinical
Part B contains 100 clinical questions covering four domains of nursing competence as defined by the NMC:
- Professional Values and Accountability: Ethics, confidentiality, consent, duty of care, safeguarding, and the NMC Code of Conduct.
- Communication and Interpersonal Skills: Effective communication with patients, families, and multidisciplinary teams. Documentation, handover, and breaking bad news.
- Nursing Practice and Decision-Making: Clinical assessment, care planning, medication management, infection control, wound care, vital signs interpretation, and emergency response.

- Leadership, Management, and Team Working: Delegation, supervision, conflict resolution, and working within UK healthcare systems (NHS structure, CQC, clinical governance).
Questions are scenario-based — you are presented with a clinical situation and asked to identify the most appropriate nursing action. The pass mark is approximately 67%, though it varies slightly between question sets due to the Angoff standard-setting method.
How the CBT Differs from Indian Nursing Exams
The CBT is not a test of textbook knowledge — it tests clinical decision-making in a UK context. Several areas catch Indian nurses off guard:
- UK-specific protocols: The NMC Code, NHS safeguarding procedures, Mental Capacity Act, and Deprivation of Liberty Safeguards are heavily tested. These do not appear in Indian nursing curricula.
- Patient autonomy: UK nursing practice places strong emphasis on patient choice and informed consent. Questions often test whether you would respect a patient's decision to refuse treatment, even if you disagree with it.
- Delegation and accountability: You need to understand what tasks can be delegated to healthcare assistants and what remains a registered nurse's responsibility.
- Drug calculation format: While the mathematical concepts are the same, the medication names, dosage formats, and units may differ from what you used in India.
How to Prepare
1. Master Drug Calculations First
Part A has the highest fail rate. Practice at least 20 drug calculations daily for the four weeks before your exam. Focus on IV drip rate calculations (drops per minute and mL per hour), weight-based dosing (mg per kg), unit conversions (micrograms to milligrams, millilitres to litres), and fluid balance charts. Work without a calculator from day one.
2. Study the NMC Code of Conduct
Download and read the NMC Code from the NMC website. Many Part B questions test whether you understand the principles of prioritise people, practise effectively, preserve safety, and promote professionalism and trust. If you have not read the Code, you are guessing on at least 15 to 20 questions.
3. Use Scenario-Based Question Banks
Avoid rote memorisation of facts. Instead, practise with scenario-based questions that mirror the CBT format. Free practice tests are available on the Pearson VUE website and the NMC website. Paid question banks from providers like PassNursing, StudyPRN, and Mentor Merlin offer larger question pools with explanations.
4. Learn UK Healthcare Systems
Spend time understanding how the NHS works: the role of CQC (Care Quality Commission), clinical governance, incident reporting (Datix), the duty of candour, and the difference between NHS Trusts, CCGs, and ICBs. These are tested directly and also form the backdrop for many clinical scenarios.
5. Take Timed Mock Tests
Complete at least three full mock tests under exam conditions (four hours, no breaks, no calculator for Part A). This builds stamina and helps you manage time — rushing through 115 questions leads to careless errors.

Exam Day Logistics
- Cost: GBP 83 for both parts (many UK employers reimburse this).
- Location: Pearson VUE test centres. In India, centres are available in cities including Delhi, Mumbai, Bangalore, Chennai, Hyderabad, and Kochi.
- Results: Available within 48 hours.
- Retake policy: If you fail, you must wait at least 10 days before rebooking. You have up to three attempts within a 12-month period.
What Happens After You Pass
A CBT pass is valid for two years. Once you pass, you can begin applying for UK nursing positions and your Health and Care Worker visa. Your employer will typically help you prepare for the OSCE (Part 2 of the Test of Competence), which you take after arriving in the UK. The OSCE is a practical, station-based clinical exam — separate preparation is required for that stage.
Common Mistakes to Avoid
- Under-preparing Part A: Do not assume drug calculations are easy because you did them in nursing school. The no-calculator rule and the 90% pass requirement make this section demanding.
- Ignoring UK-specific content: Indian nursing knowledge is a strong foundation, but you must layer UK protocols, laws, and systems on top of it.
- Studying only from one source: Use at least two or three different question banks. Each one covers slightly different angles.
- Leaving revision too late: Four to six weeks of focused preparation is the recommended minimum. Do not book the exam until you are consistently scoring above 75% on mock tests.
