A test bank for University Physics is a very important teaching resource，and it plays a significant role in process evaluation and outcome evaluation of the teaching process. We have developed a test bank that consists of 5000 problems，and has a fully-featured system and a very broad test range. It includes functions such as “tracking”，“statistical analysis”，and“updating”. Especially，using big data，the statistical analysis function provides a tool for teachers ( students ) to evaluate the effectiveness of their teaching ( learning ) and adjust accordingly.
