I would say it's not neccessary to freeze her out, as there's no bad behavior yet to punish. And the wild date thing isn't particularly neccessary either, especially while you're busy studying for exams

Instead, USE the study dates.
Studing for exams was always my favorite excuse to kino and escalate, even before I knew about PUA. If you're studying together, just develop a sound reason why you need to study at your place (or, insert prefered kino locale here), and then begin the work of seduction.
Sit close, put your arm around her incidentally as you lean over to look at something on her page, make a sexualized joke out of whatever you're studying (even if you have to look over it ahead of time and prepare some stuff).
Begin to create distraction and build a conversation that takes you away from studying. Perhaps make sure you have some props to talk about in your room--even an interesting book will suffice. Once the focus on studying has gone away you can begin the seduction as usual.
I don't know if I was too general, or if that answers your question sufficiently ased on your circumstances, but let me know, because I do have some more thoughts on it.
