What does this mean? I really like her!?

I met this awesome girl at my school. She is funny cute y extremely nice basically everything i look for. We sat together the next day and i talked to her. She seems to be always smiling and enjoying the conversation. I made extra effort to listen to her just because everything she says is either super cute or super awesome. She is the nicest girl i've ever met. So anyway today after long conversations after cl while we walked i asked her if she wanted to study. She said she has a chaotic week ahead of her then she said we should definetely meet up and review. Which confused me. then we had to go so she was like lets talk about it later. Was that a rejection? Everything seemed so right. Now that i think about it she could have been just being nice. Every single time i talked to her she seemed excited and once we start talking we cant stop. lol. Well before i get carried away in her gorgeousness of her awesome personality what do you guys think? and what should i do? I always try so that we walk together at the end. like i'd wait for her. is that ok?
