Try ALEKS. It's basically an online grind session that identifies which underlying concepts you've got wrong or haven't got, and builds you toward them organically. I recently used it to get myself sufficiently intimate with trigonometry that I don't have to stop and look things up all the time "just in case." It's not free but it works well: https://www.aleks.com |
