CH 8 – Forensic Serology Diagnostic Review
This review will pinpoint the content areas that have been mastered as well as
highlight the material that requires additional study.
If we spend two or more weeks using labs, notes and text to understand the
concepts; then you should be WELL PREPARED to answer MOST of the questions.
If you cannot answer at least ¾ of the review:
1) Review the material at least 20 minutes each evening from the START of each
chapter.
2) Use the text DAILY to supplement and reinforce the material covered in the
notes, labs and other classroom activities.
3) Come in for EXTRA HELP – whenever there is a question come and get the help
you need ASAP – don’t wait until the night before an assessment or the last
few days of the marking period when it is too late to effect a positive change.
