I'm debating which curriculum to use next year for my 16 y/o son. He's a visual learner and our current SOS is not ideal for him when doing science & math. I'm also planning to use one or the other for his Spanish this year, too. I'd like to hear from anyone who's used one or both of these curriculums and get the pros and cons of each. Which do you feel would be better for someone who is a visual learner?
