The student’s study material is the product of an in house academic exercise
undertaken by our subject teachers under the supervision of subject experts at
different levels to provide the students a comprehensive learning support tool for
the consolidation of your studies.
It consist of lesson concept maps, flow charts , pictorial representation of
chapters , gist of lessons, competence based questions , MCQ questions ,
assertion and reasoning questions, case based questions, board previous years
questions, practice papers and CBSE sample question papers.
The material has been developed keeping in mind the latest CBSE curriculum and
question paper design. I hope this material will prove to be a good tool for quick
revision and will serve the purpose of enhancing student’s confidence level to help
them perform better.
Planned study, hard work, good time management and sincerity will help the
