Dear students and teachers, I am happy to announce that this is the first anniversary of my blog 'chandrastudyroom.blogspot.com.' Just one year back on 29th May 2020 I started this blog. At that time it was my humble initiative to help the teachers and students of higher secondary classes who search here and there in the net for the perfect study materials. In this blog you will find each and every materials to quench your thirst. You have given lots of support and love to this blog and in near future I expect the same. हिंदी माध्यम के छात्र इस ब्लॉग को हिंदी में अनुवाद विकल्प पर जाकर पढ़ सकते हैं।
