CLASS 12 CHEMISTRY IMP QUESTIONS | STD 12 SCIENCE CHEMISTRY IMP (GSEB). Responsibility for standard 10 to 12 education in Gujarat lies with the State Government and various institutions under it such as GSEB (Gujarat Secondary Education Board) and GCERT (Gujarat Council of Educational and Research Training).

There is an epidemic of coronadisease in the world today. Schools and colleges are closed in India and the adjoining state of Gujarat. Students of standard 10 and standard 12 have to appear for the board examination. Students work hard in board exams. Students are constantly brainstorming on how to get the best marks in the Gujarat Board exams.

In this post, we have put important material for students studying in the standard 12 science stream. If the students download the PDF file in this post and prepare the answers to the questions contained in it, then they can achieve vivid success in the Gujarat Board examination. IMP questions of three important subjects of Standard 12 Science Chemistry, Physics, and Biology are placed.

There are important questions according to the chapters of Biology, Physics, and Chemistry. If the questions prepared in this PDF are prepared by the students then no one can stop them from passing. This file is very useful for students who intend to “pass” in only 12 sciences. My suggestion to the students who are going to take the standard 12 science exam in March 2021 is to prepare these questions and pass with good marks.
