classes

well it all depends on the person. If one works a lot, or has kids at home, then online classes are perfect; or for one that learns fast and doesnt need a lot of teacher/instructor intervention, then it would work too. If you need more one on one intervention with the instructors, then the classroom classes might be the best choice Very good topic!

For me, online class is not that affective because you cant concentrate!...It also depends to the person if he's / she's willing to learn more and focus on the online lessons!...

I think it has its own conveniences. But I think the traditional way of teaching is still the best way to teach students. Online classes are at times just taken for granted. The instructor doesn't even know if he has students listening or not. Students cannot ask questions right away. So I think in this sense, old-fashioned teaching is better. =)
