The graduation of my brother.

I have a brother and a sister. My brother is 44 years-old. He is an engineer of construction. Yes, it is somewhat late to study. One day, he got an information about the a free master's course for white workers. All expenses were paid by the government. He tried to participate in that program, and finally, he succeeded. Two days ago, he, finally, passed that course. He became a master (? We don't really say this. It only works if he got a doctorate, and then we would say he became a Doctor of Engineering). To celebrate his graudation, my wife and I went to his university, and we attended at the graduation ceremony for graduation. About 20 of his fellow students were acquired their master's degree. I really would like to appraise praise their enthusiasm for their study (This is something called passive voice- grammatically it's ok, but saying something like, "I'm amazed at their enthusiasm for their studies." actually sounds better. Also, appraise means to determine how much something is worth). After finishing this ceremony, all my familly our entire family went to a restaurant in the department store near that the university. I treated this lunch as my present for my brother. During came On our way back to my home, we stopped by my sister's house to take my sister, and my nephew, and niece over to my house. My parents and my sister's family  and my family went to a restaurant to have a dinner. My father treated it paid. We really enjoyed that time ourselves. I drank some alcohol with my father and my brother-in-law. It was so pleasant (Grammatically ok, but "so pleasant" doesn't quite sound right. "It was a great night" sounds much more natural).

Hope this is helpful. I might have missed some stuff, but all in all, I understood everything, so I'd say you're doing well. Sounds like a good night, and congratulations to your brother.
