'I taught him a course' - recommendation lettrer (for Msc studies)

Hello everyone!
This is a recommendation letter about me. What do you think about that? Please read, comment and revise it! Thanks in advance.

To whom it may concern:
I know X for two years as his teacher.
I recommend him to you. I taught him a course: the lab of computer architecture. He got a perfect mark in it: a full 20/20! I think this shows his perfect performance sufficiently and it is not necessary to give more comments about that. In addition, he was so organized during this practical course - that is so important about these types of courses. These sorts of courses are based on detecting, analyzing and then solving the issues and he did it well as an innovative student. Another aspect of his personality that I want to mention is his interest to teamwork. It's because the practical courses are generally related to teamwork activities and he could afford it along with his group members well to solve the problems perfectly. We had a time pressure in each class session to complete a whole part of the course and he did it suitably too. Finally I should point to his great mark again that put his at the top of the class.

Herby, I want to recommend him strongly as a perfect student based on my experiences at the academic atmosphere. Please don't hesitate to ask me later, if you need more information.

Sincerely

Is this written by you? If not, I would strongly reconsider using this letter of recommendation. It seems so unprofessional for a high school teacher/college professor to write like that.

I agree with qhduong, i suggest you ask a teacher/ college advisor to write you a recommendation.
