Certain features of the G&T and MSR questions are probably best displayed online with interactivity, such as drop-down menu, sorting table by column, switching among multiple tabs, etc. Even if they try to adopt the question format to a hard copy version, I'm not sure it will best prepare the test takers for the real exam.
Just my two cents. You've got a great score anyway.

Thanks for the wishes!
Yes, you're right; the online question bank did have some Graph and Table questions, but the book did not have them. I believe it would have been better if the hard copy of the book had a wider array of DI questions, apart from the Data Sufficiency and MSR questions.
