Mrs. Hendrics said "where are the books"? Correct me please if it is incorrect.
Please

There are four mistakes spotted in the sentence.Firstly, Mrs. Hendrics is asking for the books. So, it will be "asked" instead of "said" but still you can write it "said" only. But if it was in indirect speech, it must be "asked".Secondly, you haven't given a comma after said. You must give so.Thirdly, the w of where should be in capital. Lastly, you have written the "?" after the double quotes. You should write it before the quotes. So the correct sentence will be:Mrs.Hendrics asked, "Where are the books?"

OR

Mrs.Hendrics said, "Where are the books?"

Hope you could get an idea from here.

Doubt clarification - use comment section.

Maybe because he failed the classes or is very accelerated.
