hi, I have a placement test coming up tomorrow, and I'm pretty confident about all the stuff that's going to be there except trigonometry. I took trig two years back and I understood it very well. But now it's been so long and I can't even remember the basics.
Is there any website where I can go and review all the concepts of trig so I can do good on my test tomorrow?
Also, it would be wonderful if that website, or any other, included practice tests that I can take and see how well I understand it.
Thank you so much!
Try these sites.
Good luck with your placement test! :-)
