[Histonet] ASCP HTL study guide

[jdhannasch at gmail.com]

I am starting to study for the American Society for Clinical Pathology (ASCP) Histotechnology (HTL) certification. ASCP's website gives an extreme vague guide of what to study and their vague study guide requires multiple books. I am currently an ASCP histotechnician (HT) so I'm aware of how hard certification is. Does anyone have any pointer on study materials or guides for the HTL certification? Thanks in advance for any advice even if it's a small piece of advice.
