SUMMER HOLIDAY HOMEWORK 2021 - 22
CLASS –XII
Dear Students,
“The anxious and unusual times bring unforeseen difficulties but the best of human nature can rise to the challenge.” We all have within us the strength, the patience and the passion to reach the stars to change the world. Let’s not fear change; embrace it. Life is all about moving on, accepting changes and looking forward to what makes us more adaptable and stronger. The Summer Break is scheduled from 14th May to 31st May 2021. Let’s not forget that this year vacations are not meant to explore the world outside but present an opportunity to rediscover ourselves while staying home and being safe. Summer Vacation has always been considered to be the most desirable period looked forward by children when they can go beyond academics but let’s not make it a challenging situation clouded with the gloominess of Corona Pandemic. So, embark on a journey of fun and adventure by reading books, exercising, meditating, dancing and channelizing your energy in a positive manner. In addition, maintain the momentum and rigour that has been built in the learning through the last year. Plan out and complete the holiday homework. In addition, revise the syllabus already completed and check the dates for Periodic Test – 1and make earnest and sincere preparation for the same. So during this unique break when you are homebound, be a source of support and help to your parents, be positive, focused, self disciplined and do live life with enthusiasm and zeal.
HAPPY HOLIDAYS!
