Please pay attention to the fact that English letters can be represented in 2 forms depending on the context.

We can write each letter of the English alphabet as a small letter (abc…) or as a large or capital letter (ABC…). Here is a full list of capital letters.

In English, we do NOT use capital letters very much. We use them mainly for the first letter of sentences, names, days, and months as well as for some abbreviations. We always write the first-person pronoun as capital I.
