[ArchivalUser]

i am done with basic science and starting my preparation for step 1 and want to take step 1 by January 2019 then start rotations. if I am done with step 2 ck and cs by July/August 2019 in time for September 2019 applications for 2020 residency, can I finish all rotations in time to start residency in 2020 or I will be late to start 2020 residency?

I am an older student and not regular one age wise.

please reply and advice.
