Is this Korean sentence correct? 난 책을 읽고 의자가 위에 앉았어요. (I read a book and sat on the chair.)

How to correctly use this Korean verb? I recently learned the verb "꽂다" which means "To stick, to fix, to arrange,to put in a particular place, etc" the only problem is that, i'm not to sure how to use this verb in the correct context. So i jotted down a few sentences to see if i could possibly get the hang of it! -내 머리가 안에 물을 꽂았어요. (i stuck my head in water) -고영이가 위에 침대를 꽂아요. (the cat is put on the bed.) -난 책이 뒤에 책상 꽂아요. (i'm putting the book behind the desk.)

Where does this go in the Korean sentence? 저는 오늘 학교에 갔어요. [친구랑 같이] Where does "with my friend" go in the sentence before or after "오늘".
