What I do if I finish the topic but doesn't score full mark in that topic sectional?

Hi
It is likely that even after covering full topic you might not score full marks in the topic test because the questions being application based or sometimes time pressure is also there or some questions might involve few concepts from other topics as well which you might not have covered , however I would suggest you to analyze the test very well and revisit the questions which you got incorrect or couldn't solve after a few days and also revise the topics which you have covered at least once every week .
