Hi,
It is really not important from which location you want to study, but is your coaching that matters.
If one choice from the above places- Go for Ranchi-
Coaching preference- While T.I.M.E without doubt has more number of students enrolled in the country yet there are so many regions where it has to grow and create proper infrastructure and hire experience teacher.
T.I.M.E is more popular in South India while in places like Delhi, Jharkhand, Career launcher takes the cake.
T.I.M.E at Ranchi is relatively a fledgling in comparison to Career Launcher. From what I know, very few students are enrolled in it giving you very little competition and exposure.
All the best!
