Could you please kindly give some advice and share knowledge for my friend?

  1. I am planning to sit Plab 2 exam in November 21st,2019 and I got MTI offer today for IMT stage 1 for rheumatology.What will be the consequences if I took plab 2 exam and passed and after that, I joined for MTI training?

  2. Is there any difference in GMC registration of plab pathway and MTI pathway?

3.In case if I fail Plab 2 , what will be the consequences? Can it affect my career and MTI post?
Many thanks in advance!
