I have attempted IES, IAS of 2010 with one year coaching but i couldn't clear IAS prelims with shortage of 10marks. i have done some projects/professor in institution, i have discontinued it from jan-2011 due to my unhealthy(migraine). i recovered recently & wrote GRE & TOEFL within span of 1week to get admit in AUG-2011 fall itself but i couldn't done the other requirements in-time, so i planned it to JAN-2012. This my profile i wolud like to ask the question regarding my career in masters & after it. Question is whether this two & half year gap will effect my graduation or at the time of job..? (that means at visa time & after completion of masters)
Could you please tell both positives & negatives of the happened situation & suggest me with some guidelines to follow like doing some courses etc... i will be very glad for early reply from this board members & friends. Thank you.
