I also studied in Nigeria NSUKKA but i dont think its as easy as u think. u have a lot of time 2yrs house job and service to read. i grad in 2009 did house job last year thought i would write next month but still not prepared. take this time to search know all u need get all ur materials, u can get all on net. immediately u drop pens on ur final exams rest and start then. starting now u may have problems in ur final exams and not grad with ur class is not something u will ever like to remember. i don't know where u are studining but my final year in unec wasn't the type u will be preparing for USMLE.
Where are u studying?
Hope all this helps
