Final study semester!

This week last semester of my studies has started. I feel a little anxious about the classes because it will be really difficult. Also, I have to work on my master's dissertation. It will take some time to complete the review of the literature and the calculation part. I must have to present my calculations to the expert committee by winter. But despite these difficulties, I am ready to study.
This was my short note. Native speakers, if it is not difficult, please correct it :)
Thanks in advance!
