Is it better if girls studied together with boys at BIL?

Our school system was created by Turkish teachers and employers. And by their vision of best system to studying is to study without girls for boys and inversely. Honestly, sometimes it is difficult to study without girls because they bring some rays of sunshine in our life. But students don't have to choose because we are in BIL for studying.

But I believe that in principle no matter who are you studying, it can be a girl, it can be a boy, maybe an adult, but the main qualities of being a good classmate are your desire for success, being helpful, grateful, and honest.

In conclusion, I want to say that this system brings us some competition between BIL for boys and BIL for girls and it also motivates you to study.
