CBSE Biology For Class - XII

The study of biology has become more complex yet interesting over the years. The research findings of the last few decades have rekindled the dwindling interest of the learners in the subject. The CBSE has been regularly updating the syllabus for the Biology paper to make it more contemporary and relevant to the present times and the times to come. The number of students opting for biology at the +2 level has also increased gradually.

We have great pleasure to bring out the third edition of Nootan Biology for Class XII Examination of CBSE Board. This thoroughly revised and considerably improved edition of the book is strictly in accordance with the recently revised CBSE syllabus. The subject matter has been completely revised and some chapters have been entirely rewritten. Several illustrations have been improved and some new illustrations have also been added. At the end of each chapter many new questions have been incorporated which were asked in recent examinations.
