I'm not completely sure what you want to say here so I'll talk about each phrase. Here's how everything works: "My brother picked me up to university(means my brother took me there)" You would want to say: "My brother picked me up from the university" This means that your brother arrived at the university and took you somewhere. "my brother took me to university." You would want to say: "My brother took me to the university." This means that your brother took you from somewhere to the university. "my brother brought me university( when I want to tell this when i am at university)" You would want to say: "My brother brought me to the university." This means the same thing as the last one.

My brother picked me up AT the university [You are at the university] My brother took me to the university. [You and your brother are not at the university, so he has to take you to it.] My brother brought me to the university [Brought you the university would mean that he would bring the university to you] You would use "to" because it is motion from one place to another. He "picked you up" means that an event happened somewhere - the even it that he picked you up. There may have been motion toward it - your brother went to the university to do it, but that is implied.

1. the first sentence should be : My brother took me to university ( cos u two are together and he takes u there.) 2. when u r somewhere and someone will take u somewhere else on his way ur sentence will be like this : My brother will pick me on his way back home. 3. when someone comes to pick from university: My brother picked me up from the school. ;)
