Hi
shilpibansalThanks for posting
A couple of things...you mention quitting your job and entering b-school in September 2019. Hold off on quitting anything until you actually have an admit somewhere! B-schools aren't always too keen on applicants who aren't fully employed. Then, given that it looks like you are an Indian engineer, I highly recommend that you try to get to 750+ on the GMAT. There is a lot of competition from your demographic.
You mention that your husband is in France. The two best French MBA programs are INSEAD and HEC. They will require excellent stats and application execution so get ready. This doesn't give you much of a back-up plan however so please make sure you consider other options in case the GMAT doesn't work out.
My recommendation is that you get back in touch when you have a GMAT score for a more thorough evaluation.
Hope that helps!
