Good morning dear parents Kindly refer the following link of study skills module which will help your child to prepare for their academics and yield better results through school and even after school. These modules has been taught to students in class. All ppts and handouts of Study Skills modules 1, 2, 3, 4 have been uploaded. Requesting you to make sure students are making use of this module at home. Study skills module Warm regards Aavleen Bakshi School Counselor PIS Vadodara
