If you didn't know, the GMAT exam is valid for 5 years and it is really something to think about. A lot of my students are those looking to take the exam within 10 days to 3 months (many looking for a re-take boost) - but there are students out there who have no intention to apply for quite some time and/or schedule quite well. There's a particular New Yorker who I may never forget in terms of their scheduling.
This doesn't mean studying for the GMAT for 5 years, though! It simply means, for example, if you have graduated and know you want to apply 3 years from now (and have about 6-8 months relatively free in the following year), it may be good to allocate that time beforehand to studying and taking this test. It'll be one less thing to worry about when you eventually apply. Juggling full-time work/GMAT prep/app preparation can be brutal. I literally suggest to some full-time working student-clients to take sessions with me BEFORE their work day in the early morning (partly so they are fresh and alert).
