General Chemistry Std. XI (Part II)

About LIVE Paathshala:

LIVE Paathshala is venture of  Catalyst Academy of Chemistry (professionally managed multi-disciplinary research-based Institute). Since 2014 venture is delivering  Chemistry for students of Grade XI, XII and above through Real-Time LIVE  Interactive Streaming Technology. The Chemistry delivered by us  covers all Basic Fundamentals of Chemistry  including Concepts and its mode of  Applications such as  (How & When), and  its techniques to understand it at all levels of an integrated syllabus of all Boards (C.B.S.E., ICSE, STATE . . . . . .) & Universities . It also guide students about exam  techniques, How to do well in all examination related studies to achieve their Goal.

This  comprehensive course includes Tips, Tricks, Techniques, Practice problems and Applications to keep students away from Chemistry Phobia. It also guide students for selection of Carrier & also make them do well in all aspects.

Providing thorough grasp knowledge of Fundamentals, Concepts and its Applications, Create ability to  understand  applied conditions, resolve related issues/difficulties to get result oriented solutions and also to generate interest to know chemistry around us.

This program is for  students of  Std. XI (all Boards/Curriculum) who are ready for Board/ Entrance Examination. It is intended to be a condensed review of various concepts from a typical Chemistry course.  This course is a blend of video-based instruction and LIVE session interaction. This is the perfect way for students to fulfill their Dreams & to achieve their GOAL.
