hey priya
Ok here goes progressive -ve marking is like they will deduct -.25 for the first five wrong -.33 for the next five -.5 for the next and so on.
This is just an example but you get the idea
So the more you do wrong the double you pay.
this negative marking could also be -.1 or -.2 and so on and so forth.
As for the different options kaa funda i say that from, experience
In the FEb 15th CAt i had got some 10 wrong in Di rerally screwed up but my percentile read 92
while i got some 7 wrong in maths (out of 22 attempts) and my percentile read 82
the bottomline was that i had panicked in the maths section and in the last three minutes marked some answers which i was only fifty percent sure of (and got all those wrong)
And hence the idea that different options carry different negative nmarks of course this is all speculation
the classes claim that thats the way it is but the negative marking is so low initially that -0.33 or -.25 tends to even out the case and hence is justified.
I would vote for -.33 being closer to the whole idea than -.25.
Nevertheless its not that way thats for sure.
