I took the ABO test but didn’t pass it. I spent a lot of time with this study guide but there were a lot of lab questions and I didn’t recognize them. I also could not remember formulas. How can I remember them? Is there a way to remember which formula is for which question? I didn’t do as bad as others I new but I still didn’t pass and that was disappointing to me. Any suggestions are welcome.
Hi Angel,
I think the only way we can remember the formulas is to apply to the exercises (just like in math & physic). Unfortunately, this study guide doesn’t have that.
I took the abo test in nov. 2010 and I passed the test . I have only ben in this line of work for one year now but I spent a lot of time studing and looking thing up on line and that’s how I found this web sight and the test that you have I took a long with my fellow works that took the test .thank you for your help
Angel, Are you talking about the transposing formulas? Are there more formulas that I have not found yet?
