Correção de texto: My journal

Today I am going to write a little bit about my day. How it was, what I did and stuff like that.
I left home about 4am, it was a really hot morning and I mean it! So far I barely knew that the day would be much hotter. In the morning I took an exam at my university . I thought I would have a hard time because I hadn't study enough to be confident. Thank God it ended up being an easy test. The things I had learned to take the exam 'were in the test'.
