We are the students of the computer course that you are doing currently. we are really grateful to you with your dedication and efforts in the course develop. Your classes are being very funny and the content of these is correct. This is in the way to reach all of knowledges that we need. However, we want to say you that there are some points or aspects that we think you must change in order to reach the perfection. We refer to the class organization. We would thankful you if you change this method. Now we must practice on the computer in groups of four classmates. With this method only one of them can touch and to practice, and the other ones only can see. we want propose to you this option: divide the class in two groups and do shorter practices with rotating workgroups of two persons. we don't know if it is possible, but, we would grateful to you if you consider or proposal. Best Regards, your pupils
