i have reccomended this webstite to my friends who are also great vetconnexx.com i thank the blog maker .
PURPOSE OF THIS PAGE: I launched this web page to assist students preparing for IIT-JEE and NEET exams; particularly facing problems with chemical sciences.
Most of the students are afraid of JEE or NEET-chemistry part, eventually developing the feeling of aversion and end up in neglecting this high scoring subject..
Indeed, one can easily master the principles and applications of chemistry. Celebrate with us. Help us celebrate the th birthday of longtime JBC editor Herbert Tabor! As part of our festivities, we invite you to send your best wishes, share photos and record your fondest memories of interactions with him over the years.
