What does it mean if she agrees to study?

We're both in a college and we've only known each other for a a little less than a month. We talk to each other when in cl and some text messages. when we talk to each other we both smile and laugh and act flirty towards each other, however, the majority of the time i am the one who always initiates the convo. i asked her if she wanted to study before our midterm. she said sure and told me she was going to a review session and if i was also then we could study more after that. any advice or tips is appreciated. thanks :)
