My dear Friends/students
Wishing you all happy sankranti and happy wishes to Ugadi in advance.
As I have uploaded a New pattern (NCERT + PUC BOARD GUIDELINES) Model question paper of MATHEMATICS for all the science students (For the classes XI, XII-PUC1 AND PUC2) Who are writing Annual exam -2014.I designed this model paper according to latest syllabus.I request all science students to make use of this question paper to secure maximum score in their Annual exam 2014.And also I request all my friends and students to help other students by sharing this model question paper.
Wish you all the best for Annual exam-2014.
