Beat The GMAT a GMAT & MBA community

Hi, I am scheduled to take the exam June 1st but I am thinking of postponing by my exam date and registering for a kaplan anywhere advantage course? But I noticed that their are no dates and times on the website it wont open?

Also I am hovering around the 600 mark 590ish, should I enrol in the advantage or advanced course? I have heard that I could do the advantage course then the advanced course after and just pay the difference of $50. Is this correct? I feel this is something I would do, would you just recommend enrolling in the advanced course then?

Also the IR portion was not listed on the timetable for the class. Is it just via on demand videos? Is there many practice questions for it?
