Why my answer is not correct?

I write: SELECT COUNT(*) FROM books AS 'scifi_book_count' WHERE genre = "Science Fiction";

But it is still showing incorrect answer. Why?

You're close, but putting an alias after a FROM clause creates a table alias. What you want here is a column alias, which is part of the SELECT clause:

SELECT COUNT(*) AS "scifi_book_count" FROM books WHERE genre = "Science Fiction";
