Mistake

 * "[A particular point space] $X$ is not weakly countably compact since any set which does not contain $p$ has no limit points."

However, this is true only of an infinite particular point space.

By definition, a space $X$ is weakly countably compact iff every infinite subset of $X$ has a limit point in $X$.

But a finite particular point space has no infinite subset.

So a finite particular point space is weakly countably compact vacuously.
