Hum, I think you would be better off just taking it again by itself to be safe!
Do you still have time in your class right now to pull up your grade?
Study groups, tape record your class, speak to instructor, see if you need
more time on your test taking through DSPS, and any other ways you can
pull up your grade now... Either way, you will be fine and you will retain
it better the next time around!
Stay positive and only focus on this one class if you can?
At my college Chem had to be taken first before taking this class... Keep us posted on what you decide.
