a short summary for my grammar class

In the class of At yesterday's class, Professor Xiang introduced the teaching plan syllabus and constitution of scores grading/scoring methods of his course to us. In my opinion, his introduction was simple and clear, which made me it easy for me to understand. He also inspired us to build up set an ambitious goal and work hard for it. These words enhanced my self-confidence.
But there were also some weak points in this lesson. Firstly, the words’ size of Powerpoint font size was too small to see. Secondly, Professor Xiang spent much time telling stories and finally failed to finish the class on time.
Here I put forward some constructive suggestions. First of all, enlarge the words size of PPT the Powerpoint/slide presentation and highlight some key words. Second, Professor Xiang should manage time reasonably. For example, he can introduce the contents about of the course first, for he will be able to hold cover this part easily. Then he has plenty of time to tell the stories of study his studies. I'm not entirely certain what you mean by "stories of study". If you give an example, I could suggest a better phrase.
