Hello folks,
DI section is turning out to be a nightmare for me. I goof up with the calculations, given that i never did calculations to such extent all my life!. The ans I get by appx tech are never close to the actual ans, In fact i waste a lot of time even approximating the ans. and if i gather all my guts to religiously solve the q without appx I end up doing so many calculations that i even forget what i wanted to find out. In short i am wasting a lot of time! and that too for what? negative marks!!:O This in effect is messing my QA scores. I am in need for quality advice. Is it essential that i mug up 30x30 tables and fractions and bla bla, for a good Di score.?
All the DI Gods and Goddesses please come to my rescue :(.
