An unforgettable presentation for me.

A few days ago, I have had finished my first presentation in for my college. I did not present it in front of 300 peoples and but I still felt 1000% extremely nervous during my presentation. Because of my major, I needed to say some names of drugs and surgeries in English, which are too tough to speak it out loud. Even though I have practiced for this big moment for almost 10 days, my hands were  still shaking distinctfully.
Fortunately, I could achieve what I expected of myself for and my friends felt thought my presentation was so great. The professor feels that I am doing good as well. But I think I could be do better next time.

P.S. I am confused about wondering even if I could can read the articles in English smoothly than  ever. When I am writing, the range of vocabulary I use is so poor. How could I deal with this embarrassing problem. Thanks. :)

A unforgettable presentation for me.

A few days ago, I have finished gave/made my first presentation in my college. I did not present in front of 300 people <em>(this is a strange way to express it - how big was the audience then?)</em> Although the audience was quite small (less that 300 people), and I still felt 1000% extremely nervous during my presentation. Because of my major, I needed to say some names of drugs and surgical procedures in English, which are too difficult for me to pronounce tough to speak it out. Even though I have had practiced for this big moment for almost 10 days, my hands were still shaking distinctly/perceptibly.
Fortunately, I could achieve what I expect had hoped for and my friends felt my presentation was so really great. The professor felt I am doing good work as well, but I think I could should be better next time. 

P.S. I am even more confused about even how to write I could read the an article in English that reads smoothly <em>(I am only guessing at your intended meaning, I may have got it wrong)</em> than ever. When I am writing, the range of vocabulary I use is so limited poor. How could can I deal with/address/solve this embarrassing problem. Thanks. :)
