Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
You have a good profile. If I were you, I would focus on the application essays and not on GMAT as you have already taken GMAT four times. Dont worry about it. You have decent academic score.
LBS and INSEAD will like your international experience at Shell. For your leadership essay, you will have to come up with something from your extra curricular activities. If you can write excellent essays, I am confident it can compensate other areas in your application.
You have to project your role in women’s rights, fund raising efforts, etc in your essays. Business schools like this stuff.
Your post-MBA goals needs more polishing. Speak to few current students and alumni of your target schools. A small career progression doesn't excite most of the top schools, esp LBS and INSEAD. You need to dream big.
Oxford, Cambridge, and HEC should not be very difficult for your profile. Focus on LBS and INSEAD. Good luck!
