The car theory test has two parts taken in one sitting. First, 50 multiple-choice questions in 57 minutes, of which you need 43 correct. Then the hazard perception test: 14 video clips containing 15 scoreable developing hazards, scored 0 to 5 depending on how early you spot each one, with a pass mark of 44 out of 75. You have to pass both parts in the same sitting; passing one and failing the other means retaking the whole test.

Yes. You cannot book a practical driving test until you hold a theory test pass certificate, and the certificate is valid for two years. If it expires before you pass your practical, you have to take the theory test again - which is why most people book lessons and the theory test in the same few weeks rather than waiting.
