i asked physics question paper and u r showing mathematics and bio and all.... brainless haa???????????????????

if we write that answers na we will gets zero 0 out of zero 0,that's sure...so plz better improve ur answers and all so that students can write the answers correctly and pass first of all students are facing to pass bcz of fake corrections of boards, so plz re write the answers correct otherwise don't post anser sheet post only question sheet,

[QUOTE=Unregistered;626264]Give me question paper for PUC Second Year science Supplementary examination of 2014

please post all p c m b model question paper for supplementary 2015 I felt very bad am not a student to fail, with full heart am telling,

this time 2015 2nd puc board correction was pathetic, i used to score 100 on 100 in mathematics for me in the paper they have given 25, my whole family is shocked to know that a brilliant student like me has failed in the 2nd puc final exam. :P so please let the supplementary atleast be good

Plzzz let question paper be bit esy to pass fr the avrage student u r aim shd nt nly on the setng of paper tnk abt average students

Electronics supplenentary question paper

Plz send supplementary question paper for chemistry.i am not sfail student. But i don't know, how this is happening. Plz send

Can u plz say question for 2018 supplementary
