I read the Shit test 101 and the intro to shit test articles on the sidebar. Is there anyplace else where I can get more material on shit test?

I feel I only understand the concept superficially, I want to know how to identify a shit test and how to handle them with some examples, if possible.

I have met a few women recently but I have noticed a few women give shit tests blatantly and a few of them don't really give them. Should I mark that as a sign of interest/disinterest or am I reading them wrong?

And if i am not getting any shit test from a women to pass what should I do to build interest?

Any help is appreciated.
