Ребят, помогите написать небольшой рассказ на тему MY MOST DIFFICULT…

Last summer i spent 1 month studying in London in summer school. It located in the center of the city and its name UCL. I may say, that it was rather difficult at the beginning to understand typical british language cuz i prefer American way of speaking. But, one week late it became normal. Nowadays, i speak both languages well. But still don't know grammar
