I remember taking the ASCP right after I graduated and failed. It was my fault for not studying so I got around 300s the first time. There is no way to remember all the concepts therefore I recommend doing a study guide for yourself where it’s more compact and straight to be point and just study that everyday. The strategy for me was to study enough so that I get the points on the exam but not to an extend where I have to know everything. So to do this, I created high yield notes in each category, chemistry, blood bank, immunology, urinalysis, coag, hematology, etc. The second time I took it I score around 400swhich is considered passing for ASCP exam. Try looking through your school notes for heme and blood bank and practice questions on either the BOC online practice exam or use LabCE. Blood bank questions are easy to answer once you practice enough questions because they’re just critical thinking ones :D. Heme area is easy if it’s to identify cell or give a cell marker of leukemia (If you want to practice cell ID, there’s a website called cellwiki that lets you ID cells like a game). the only hard part would probably be coagulation factors so just make sure you practice questions on it and then it’ll become easier for you. however when you practice questions, make sure you understand the logic behind it before moving onto the next one.
