Can someone correct me, please!

Can someone from the moderator's community help me to check my answers to those questions sent to me via email from my overseas friend. That's an example of an English TOEFL test and placement test. I tried those questions mainly just for fun; to gauge my english standard, so that i will know where i stand.

**Correct me if i am wrong** and i do not need severe criticisms from people who think they are far more superior than me.
