About
Feel free to ask anything. Email - aufbauchemistry1@gmail.com
"Aufbau" in German means "Building"/"Construction". I want this platform to become the Strong Base of your chemistry conception Building Unit.
My goal is to provide the exact kind of guidance (for both MCQ based and DESCRIPTIVE ANSWER-WRITING based competitive exams) which I couldn't get during my struggle period.
It will be my pleasure if I can help you achieve success in Combined Geo-scientist exam, Csir-Net,Gate or any chemistry related competitive exams. I know the preparation time is hard, it takes a toll on your physical and mental health, so take care of yourself, be assured that your hardwork will pay off in one way or another and be positive.
Intro- Grad & Masters from Jadavpur University, M.Tech in Applied Chemistry from IIT Roorkee, Ex-Research scholar of IIT Madras, Currently engaged as a Chemist in a chemical analysis based job profile.
β€οΈThanks & Wish you all the happiness in the worldβ€οΈ
