[Areeb88]

Hi Im an IMG studying now for step 1. Im hoping to finish all the steps and apply for residency in the 2016 Match. I havent booked any dates (cause = fear)
When should i book my step 1 test date? Witch 3 month period should i register for? (planning on Feb, March, April period)
I want to take step 2CK in April or May and CS a month after, or vice versa?

HELP! Im kinda lost right now! focusing on finishing kaplan and first aid so i can start with the Qbanks!

2016 Match means the current season for which applications have already begun in September 2015 and results of the match will be announced in March 2016.
You mean you're aiming for 2017 Match, for which applications will begin in sept 2016 and results of the match will be announced in March 2017.
Considering that you haven't even started Qbanks and NBMEs yet, 2017 match will be pretty tight. Unless you just graduated within a year and had an extremely solid foundation of medical knowledge during med school, it's extremely difficult to get done with all the exams within the next 10 months.
To get a realistic estimate of things, take an online NBME soon to see where you're at. Once you're within 20-30 points away from target, go ahead and register for the exam. Feb-March-April sounds very much, but you have to take an NBME, if you're above 200/210 surely go ahead and take that eligibility period. But let's say if you fail the NBME, my advice would be to study further do qbanks and once you're atleast passing NBMEs then proceed with the application process.
Good luck!
