This is what happened today

To dry the papers, I arranged them one by one on the table.

【This makes sense but it feels just slightly unnatural to how you would tell an anecdote or story. 

Generally you describe what was occuring (getting ready for class) at the time you made the discovery or something else happened  I.e if you were eating and a friend came it would be 食べているところ友だち来た sort of thing.】

I was getting ready to go to an English class today at University, when I found out that my papers for it were all wet!

To dry them I had to lay them out one by one on my table. 

If you want me to try and explain anything I can give it a go :)

Introduction

My main interests are mathematics, psychology and history, also I'm keen on learning foreign languages.

I made this post because it would be strange for me to post other entries without properly introducing myself.

Introducing yourself properly is one of hardest and most important things in life. Why? Because people make opinions about us based on their first impressions. (I think because we're dealing with "people" and "opinions" which are plural a plural 'impressions' sounds more natural.)

A good example of this be my job hunting; at first I was sending out just my resume and nobody replied to it, but when I added my/a letter of application (We often call this a Cover letter in British English) and added some graphics to my/the resume I started receiving replies and (I would say "was successful in finding" instead of 'found') found one part time job in promoting websites.
