#56 yograjprakash 20150506 14:05without hardwork chemistry cant b scored........hardwork n our concentration is very

important

#55 sankarrocks#q%$# 20150424 15:32I think by paying attention and by hard work we can access that chemistry is quite easy

#54 Suzzane 20150424 11:54Class 11 chemistry is quite easy. Through hardwork and determination we can pass out withflying colours. No dream is too extreme

#53 ManirujjamanAkash 20150415 08:51XDD, love chemistry too :3

#52 AbhishekChatterjee 20150414 08:43It's mentioned that is 201516 syllabus but actually is the 201415 syllabus plz give thelatest one.....

#51 ADITIKUSH 20150406 11:41ENJOY 11TH 12TH 2015 2017 LIFE INSURANCE !!!

#50 sakshigaur 20150405 12:55i love chemistry and maths and i opt pcm next year i praying that next week my interviewgosuper and i also worried for it
