Hi, can someone give a look to my cover letter, I'm not sure if the grammar is right, so I would like some suggestions to how make it better both in grammar and style. Thank you in advance.

Dear Mrs. Name
I’m writing to apply to University of Strasbourg, Master Caweb, currently I’m attending the 3-rd and the last year at University of Naples l’Orientale, Department of comparatives cultures and languages. I plan to graduate from my university at the beginning of autumn 2018, even though I’m still finishing my studies.
I’ve been studying languages for a considerable amount of time, first at high school, I’ve studied English, French and Spanish and then at the university English and Japanese. So, for past few years I’ve been inquiring in what ways should I apply them and what possible choices I had and I came to conclusion that I wanted to dedicate myself to a creative and dynamic activity such as writing and at the same time being able to use all my skills.
In 2010 my life completely changed, I moved to Italy and had to start new school, find new friends, adapt to new context, learn a new language, not always it has been easy but I learned how to overcome difficulties and take positive from every situation. In the new school I tried myself in different activities: from languages courses to art tour guides in museums, it was very edifying part of my life as I learned that everything we do can lead us to greater things, so in 2015 I won the scholarship for the 3 weeks study trip in England with my school, I was very excited at the idea of visiting the city I always dreamt of, London.
I’ve always tried to improve myself and my skills, I’ve attended different extracurricular courses, such as data entry and web copywriter, the last one has been the most valuable as I could approach directly to web content creation and could learn different techniques behind a simple text that appears on our screens. I’ve learned in which way the word choice can influence the image of the enterprise and can improve its place in the market.
In 2017, I wanted to give my university life a turn and I applied for the Erasmus+ Studio exchange, even if at that time I was only in my 1-st year and I only had passed few exams. I thought I was out of competition as there were students from 2-nd and 3-rd year as well, but to my delight I found my name on the list of that students who were going in Erasmus. The next 10 months in France were simply as great as I expected them to be, not everything was simple and I had had some problems during my stay but once again I learned that I could solve any issues and take lessons from it.
I look forward to studying at the University of Strasbourg and living this marvelous experience that will help me to strengthen my skills and to start my career.

Sincerely,

Hi, there are quite a few things to change and since I can't copy and paste your letter for some reason, I'll give some advice instead.
Seeing that you finished your school, I don't think it's a good idea to use the Present Perfect tense in this case. Also, the structure has to be somewhat homogeneous - if you use 'at school', keep doing that throughout your letter (I've noticed a few in the school/at school variations). 
...from the 2nd and 3rd year as well...
...of those who were taking part in Erasmus / who were participating in Erasmus / who had been nominated for the Erasmus scholarship...
...simply as great / not everything was simple... - better to change both to avoid repetition 
Marvellous (double 'l' if I reckon correctly)
Noticed you were using 'dreamt' as past participle in your letter, then again, stick to homogeneity - learnt instead of learned.

Dear Mrs. ...
I'm writing to apply for the Master programme in ... at the University of Strasbourg. Currently I'm finishing my Bachelor's at the University of Naples l'Orientale, Department of comparative cultural and linguistic studies, and I'm planing to graduate at the beginning of autumn this year.
I've been studying languages for a considerable amount of time, first  English and French in high school and then English and Japanese at the university. For the past few years I've been inquiring in what ways I could put my knowledge of the above-mentioned languages to use, exploring the best options for me, and I came to the conclusion that I wanted to dedicate myself to a creative and dynamic activity such as writing, which would allow me to use all my skills.
In 2010 my life completely changed when I moved to Italy and had to start all over again in another school: find new friends, adapt to a new environment and learn a new language. It wasn't easy for me, but I learned how to overcome difficulties by finding the positive side of every situation. In the new school I gave a try to different activities, from language courses to guiding art tours in museums. That was a very edifying part of my life because I realised that everything we do can lead to great things after winning the scholarship for a three-week study trip to England in 2015. I was very excited about visiting London, the city I had been dreaming of.
Since I've always sought to improve myself and my skills, I've attended different extracurricular courses, such as data entry and web copywriting, the latter being the most valuable to me as it taught me a direct approach to web content with different techniques that create the text we see on our screens and how the word choice can influence the image of an enterprise and improve its position in the market.
In 2017, I decided to give my university life a turn by applying for the Erasmus+ student exchange program despite being only at my first year and having passed only a few exams. I thought I had no chance as the students from the second and the third year were applying as well, but eventually, to my delight, I found my name among the Erasmus scholarship holders/ on the list of the students who were to go on Erasmus exchange. The next ten months in France were simply as great as I expected them to be, even though I occasionally had problems during my stay, from which I learned again that I could solve any issue and take lessons from it.
All being said on my behalf, with hope of receiving a positive answer, I'm looking forward to possibility of studying at the University of Strasbourg and living a marvelous experience that will help me to strength my skills and to start my career.
