Successfully flunked prelims this year with this in mind "First attempt bahut kam logon ka hota hai" :P
Jokes apart, this happened because I gave up too early .. so one of the learnings is not to give up 1-2-3-5-10-20-30 days before exam even if your scores are low in test series or if you feel that you are not thoroughly prepared ..
ATB to all :)
Edit : Also, trust your hard work.
