Really? Are these sentences wrong? I don't get it.

-Everything seems fine.
-The salesman was expecting to present his product at the meeting, that he would have time to show his slide presentation, and that he would be asked questions by the prospective lawyers.

-The doctors who attended him said that he would get well soon.

-I will surely remember this little fiasco.

-What did you do and where did you do it?

Really... These sentences are wrong? I don't get it

-That everything is fine seems.   That everything seems fine (but this is only a partial sentence. It cannot exist by itself)
-The salesman expected that he would present his product at the meeting, that there would have been time for him to show his slide presentation, and that questions would be asked by prospective lawyers. (This sentence is awkward but correct)
-The doctors who attended him said that he will get well soon. 
-Count on it that I’m going to remember this little fiasco. ("count on it" is an idiom; it means that something is "guaranteed")
-What and where did you do it? (this is awkward but correct. It is something you would hear in English speakers say, but it's very bad English).

My advice: all of these examples are difficult to understand for someone learning English. Don't get too frustrated by trying to understand them.
