That's right. It makes no sense. As Andy said (look again at post #3). It may help you to look up overwhelm in the WR dictionary.So if I say: Many people are overwhelmed as to how to overcome the obstacles.
That "overwhelmed as to" make no sense?
No, grammatically it is fine, but being confused is not being overwhelmed.Is this better?
