Help me, please, i feel headache

In both of these pictures I can see people studying. But here the similarity ends. In the first picture I can see a group of young students, mostly girls,and their tutor. Students are sitting in front of computers, so I can guess that it's kind of computer class. Classes like this are very popular worldwide because you can find so many new things attending them. What I like most about this type of classes is that you can find groups with different levels of education. I mean you can find groups where people are learning some basics as in other groups people are learning something more advanced. In the second picture I can see young people in the class with their teacher. I think it can't be a lecture because it seems like they are discussing something, so it must be kind of practice lesson. I don't mind both ways of studying. But I highly recommend the second way of learning. I suppose that having a man who can explain everything in real life, you know what I mean, can be very supportive while studying. To conclude, both ways of studying are awesome, but having a contact is the most important thing
