Oh cr*ap. know how you feel. There's lot of opportunity to improve your score. Decide what more important. Apply now or wait to get the score you need to apply the uni's you want.
I'm studying for the GMAT and writing business school essays. Not something I would recommend.
If you had a large score drop it could be due to stress or exam anxiety. Go see your doctor to get it checked out.
You can definitely improve your maths. I would recommend changing you study approach. I needed to improve my maths and I found magoosh
really helpful. I also got a maths tutor which has been really helpful. If you need to brush up on your basic maths try khan academy.
If doing an MBA is really important to do now rather than waiting a year. Check out the part time options. For uk schools I don't need to sit a GMAT. Your local schools might have something similar.
If you work on your timing it can make a big difference to your score. Small changes can make a big difference. Check out MGMAT blog posts for timing strategies. Egmat
strategy webinars might also be helpful.
I recommend sitting you GMAT in may or June. Then you have three months to write essays and apply to business school in round one. You will also the chance to do research for the schools and find the ones that really suit.
Take a deep breath and take a couple of days to think everything over before you make any decisions. Good luck.
Feel free to private message me. I had to move my maths up from the 20 percentile. I've now got it to about the 50 percentile but struggle to get the score to show on test day. I have been there.Posted from my mobile device Posted from my mobile device
