Hey, I feel like I have been starting too many threads, so I hope its okay to ask my question here. What workbooks (less expensive than art of problem solving) would be good for Algebra-Calculus for DD13? She is trapped in her schools curriculum with no way to skip grades, so she will have to go on with Algebra I next year unless we choose to skip Algebra I. Do you think that would be a good idea? She took an online Texas EOC final examination for Algebra I and got a 95%, and she felt she just made a simple mistake on the ones she missed. So maybe a workbook that would make sure she understands all of Algebra I before skipping?
