Um...what does this sentence even mean?
Blocked websites on a school's computer network are blocked for very good reasons. Answers.com will not give any information for unblocking such websites.
Yes , there are a lot of websites that has videos school related :) example of that is youtube :)
Most school websites usually post the dates of upcoming events on their websites. Although it isn't the case for all school sites, I suggest looking at the website of the school you are interested in.
It depends what websites your school blocks. But I suggest you ask former students what websites they used when they were in your grade/school.
I am sure that all schools have high school websites. The school always needs teachers to have websites if they don't, so you can see what type of homework there will be that night.
