How hard are Study.com Finals?

[allvia]

do a practice final, if you can pass that you can pass the real final. if you can't, go back and study and try again.

i have never failed a Study.com final and i've done 25ish courses with them.

Yes, they offer you practice exams as well.  You can take a few and get a good idea of how you stand; I usually take 2 or three practice exams just to know I have a solid understanding. The questions on the practice exams will not be the same, just similar to the final. Again I suggest you go through the flash cards first (very quick process, refreshes your memory).  If you do well on the quizzes you're likely only going to need a grade in the 50% range to pass the course - but better to get a 80% on the exam than a just passing 60%.  I've never had to retake one, even on subjects that were unfamiliar to me before the course (or those subjects that were boring as all...well you know, ha)
