I just registered for that Patho course through Nebraska online. It cost more than $1000! In addition, you'll need to pay for 6 proctored exams! Ridiculous. I haven't started yet but if you have, please let me know how long it took you!
The patho course at NL has 6 exams, 1 for each unit. You need a proctor which you'll have to pay seperately each time you take the test. I'm paying a proctor at a state college which costs me $20 the first hour and $10 every additional half hour (cheap compared to private learning centers). The advantage is that there is no cumulative test at the end.
It was pretty easy! I personally didn't need the book as much as I thought I would. Study and understand all the info in the syllabus before you take the quizzes and you'll be fine. If you bought the book, it's a good reference but everything you "need" is in the syllabus. Good luck!
