some of these problems are really off the wall and insanely difficult… I figure if there are some WTF problems then consider them out of the realm… good to put it all in perspective. I remember for L2 i literally did 7 FI problems and were so discouraged by their level of difficulty I just stopped… and it all worked out
@pimp, could you pls share with us on which questions are not relevant and which ones are important? Appreciate your help!! Thanks.
