Preparation Help! Finding it difficult to improve from 480 to >650

Hi everyone,

I wrote the GMAT exam on Tuesday and got 490- far far away from my target of somewhere between 650 to 700. I feel crushed and beaten. I have never felt this stupid in my life before (ok, I am now done with feeling bad).

I took the first mock in Mid February after looking through MGMT PREP books here and there and got 480. I underestimated the exam so thought it would be an easy ride. The one line drill questions were not difficult at the end of the chapters but the GMATPrep questions were very different. This score meant that I had to improve verbal and quant equally.

Mid February to end of March:Went through MGMT and GMAT club quant book. Created formula sheet and did questions that I downloaded from GMAT Club- Thank you for putting all these resources together.

Then I did Quant Review questions. Doing questions became easier so I thought I was improving.

March to mid May- Signed up for E-gmat and went through their question bank. I moved forward through the sections while also doing Official Verbal review questions. IN the end I was getting SC at 70% accuracy and RC and CR at around 80%.

Mid May up to May 23- I started doing Score800 mock exams and realized I had forgotten all quant. So I signed up for Math Revolution Course and were able to solve most of their worksheet questions but could not apply to OA questions.

Mental challenge- From February to the time I wrote the exam, I have consistently felt overwhelmed, lost, hit by a bus and dazed. Honestly, I am not stupid... I have a 3.8 (out of 4) GPA and I am a self taught investment analyst. I wrote a 14 hour exam last year around this time to get a designation. I don't burn out easily or give up but not seeing any improvement with 2 months of studying ( I work full time~ 45 hours), I am feeling really hopeless. I felt so burnt out by the end of last week that I couldn't even look at a question without almost breaking out in tears.

I am reaching out to this wonderful group of people to ask for help. Please help me pave a path. I would like to focus the discussion on why this may be happening and what my next steps I should take to overcome both mental barriers and knowledge gaps.

I was planning to apply for INSEAD Jan 2018 Start (3rd round) which I have now pushed to September 2018 (1st round). I am hopeful that a plan and resources will help me achieve my target in next two to 3 months.

I am not giving up and I know you guys won't let that happen.

Thank you so much for your time and help- I appreciate it very much!!
