Abstract： In this study， the Suke platform is applied to the difficult points' teaching of physical chemical. The difficult knowledge and key points constructed into PowerPoint conversion courseware， quick drawing micro course， light courseware and other network teaching resources are timely given to students for online parallel teaching before and after class. The preliminary implementation results show that the online parallel teaching mode of difficult points based on the Suke teaching platform can effectively solve the main problems existing in the current difficult points' teaching of Physical Chemistry， expand and deepen the benign interaction and communication between teachers and students. The mode can strengthen the supervision of students and control the students' mastery of knowledge difficulties and key points by using the three-dimensional data analysis and comprehensive teaching quality monitoring system provided by the Suke platform. Through a semester of practical application， the online parallel teaching mode can effectively improve the teaching effect， and the students' evaluation of using the Suke micro class to assist the key and difficult points' teaching of physical chemistry course is good.
