The recent post from GMC website has given the final date to setup GMC account
and IELTS course submission.
It’s given as there is a year gap between the IELTS submission and PLAB.
So when should one take IELTS if one is about to take PLAB on November 2023
So, in order to book PLAB 1 in 2 November 2023, you have to have GMC online ready and IELTS/OET passed and results submitted by 1 December 2022, and that booking will open on 8 December 2022.
