Passed my final exam on 12th April 2021 (I already had PER signed off and ethics completed).
Sent membership application on 12th April 2021 at 8am.
Email confirmation of membership acceptance received on 14th April 2021. Paid £258 fee on the same day.
I checked today (15th April 2021) and it says I am a full member on the portal. Also when I download the letter of good standing it confirms my membership.
I could not find a pdf membership certificate on the portal so I guess I will need to wait the 12 weeks for my physical certificate (not a major issue would just look nice on my wall).
