My (1) Life in London

I study English at a school in the centre of London. I have lessons from 8.45 a.m. to 12.00 a.m. After that, I usually go somewhere. Certainly (2) Most of the time, I don't know where I want to go and so I look at the map and choose some interesting places to visit. for visiting. For example, yesterday, I visited Green Park and St James Park near Buckingham Palace. These parks (3) are were so beautiful and I was really impressed by them. I've never seen such a variety of geese before. It is so great to see some wildlife spots in the centre of a big city.
Today, I (4) had been walking along the Regent's Canal for about two hours and it was also great.

Hi Dariy,

Do allow me to provide some suggestions:

(1) There are different guidelines on writing titles. We capitalise the first letter of each word (i.e. Life) except for prepositions (i.e. in). 

(2) "Certainly" is used to express the meaning of definitely or without a doubt. I presume that you wanted a word that expresses frequency. Therefore, I used the phrase "Most of the time".

(3) We use present tense (i.e. are) here, as the parks are still there as you were writing. 

(4) We use past perfect continuous tense (i.e. had been + verb-ing) as you walked for a duration in the past and you stopped doing so in the past as well. If you use present perfect continuous tense (i.e. have been + verb-ing), it means you were still walking as you wrote this post.

I hope this helps you.
