So I've spent the past two months working on my graduate school application essays, and I've recently started to study for the GRE, which I'll be taking on November 6th. In recent weeks I've been feeling as though my application is not a very strong one, especially when it comes to my resume. Because of this I've been thinking of delaying my application for a year so that I can boost my resume through another job or a study abroad type experience. Doing this would also give me ample time to study for the GRE. So instead of applying for the 2018-2019 cycle, I'm looking at 2019 to submit my application. Those are the bare details of it, but my problem is how I should let my recommenders know. I feel that it's wrong to ask them to wait a year, but then again they might appreciate having more time to write (I'm applying to two programs with deadlines in December and January). This isn't something that I've decided to do for sure; it's just something that I'm considering. I'd just rather let my recommenders know in the best way possible and without losing them somehow should I decide to do it.
I appreciate any advice.
