Hello and welcome to MHB, Vi!
We have lots of problems here in our math forums, POTW forums and Questions from Other Sites forum that have complete solutions given. Those would make excellent practice problems to which you may compare your solution to the given solution to see if you are correct, and perhaps to gain additional insight. Please feel free to ask any additional questions in those threads (except the POTW threads which are open to POTW Directors only). If you have a question about one of the POTW problems, you are encourage to begin a new thread in the relevant math help forum to ask for help or clarification.
Also, if you have any questions/comments about the site (feel free to post in our Questions, Comments, and Feedback forum) or using any of our features, you can ask me or another staff member.
We hope you enjoy your time here and find it productive as well.
