My normal day.

I usually wake up at 7 am and I exercise for 30 minutes. I have breakfast at 8 am, then I go to school at 8.30 am (don't bother with the fullstops in am and pm; no need to repeat the am either) 
I have a lunch after I finish my morning class at 12 midday a.m. and in the afternoon I come go home or stay in the library in afternoon. I do my homework in the evening.
I read news for fun - usually read news about new technology, such as new smartphone models, new electronic models, etc. (since you say 'such as' don't repeat with 'etc.' just use one or the other, not both). I also listen to music in my free time, and my favorite music singers are Britney Spears, Justin Timberlake, Bruno Mars, etc. I love to watch action movies, such as 'Iron man', 'tranformer', 'transporter' , etc.

Use more conjunctions to make the sentences more complex and interesting.  12am and 12pm are confusing and incorrect; just use 12 midnight or 12 midday. 12 is neither ante nor post so in fact 12am and 12pm dont exist, except for digital watches
