Could you help me correct my sentences.

2, what embarrasses me most is I went......

3, the thing that makes me embarrassed most is I went...... (you could also use "the most" in this and the above sentences)

4, the thing that surprises me most is Tom can do many things on his own without asking for help.

5, what surprises me most is Tom......

6, I like Tom the most in out of all my students. ("out" is optional, however, it is used most often in sentences like this).

7, I don't believe what Tom said the most among them three. (I would say "I don't believe that Tom speaks the most among the three of them.")

8, Lily is the one I don't like the most. (I would say "Lily is the one I least like" or "Lily is the one I like the least")

Note: sentence 1#, 2# and 3# mean exactly the same thing?
