The moment has finally arrived!
You're getting registered as a doctor under the GMC. Congratulations, you're that much closer to achieving your dream.
Now let's get back to what you have to do.
If you are taking PLAB 2 after October 2018 - then there is NO separate GMC ID Check for you. The ID check that happened/will happen on the day of your PLAB 2 exam is enough. The PLAB 2 booking confirmation email will direct what documents you need to bring and that's it.
If you are taking any other route of GMC registration other than PLAB - You will HAVE to attend an ID check in the UK for GMC registration.
