5. Use your notes to write a formal letter of complaint.

Dear Sir or Madam,

I’m writing to report about the new official website of our school. Because of technologically advanced, teaching on social media platform is also more popular. However, there are some problems with our new website and it leads to some consequences.

Many students told me that the website is very hard to use. That is also one of the reasons causes bad academic result at school. Specifically, the size of the letters is very small, so they can't read it clearly. The second one, it doesn't update the knowledge that the students learned at school. Therefore, it's very hard for them to review the lessons. Last but not least, they have to do homework on the website, but when they submit, it doesn't save the result. 

Because of those reasons, the problem needs to be solved because it affects directly to my students and their results as well as their eyes. 

In conclusion, I find this problem irritating. Unless there is a change in the format, update, and design, both teachers and students will feel disapointed and loose motivation.

Yours faithfully,
