Any suggestions on how to overcome my exam anxieties?

Hi there...

A little bit of history. I sat for my first GMAT and got a 580 (Q45, V25). I expected that score because I was not prepared for it at all. I underestimated the gmat and just practised questions without going through the fundamentals. (In fact, I took the GMAT with just slightly less than 2 months of preparation!)

In December, I spent the entire month learning the fundamentals of Verbal and Quantitative. I got to admit that I didn't practise much so at the next mocks, I got 580 again (Q44, V26). For the next 2 weeks in January, I decided to review content per topic and start practising questions with ascending level of difficulty. I just took the mocks and I got 560 (Q39, V28). I am happy that my verbal has improved. It seems that the strategy worked. And I will keep up with this.

However, I am worried about my Quant. I reviewed my Quant and I realised that I could do 9 out of the 15 questions I got wrong. I felt that my mind was a blank and I am suspecting that I could be experiencing a mind block during the exam. I might be feeling fearful and intimidated by the Gmat. After all, I have been trying very hard at it.

My Gmat is scheduled for the end of February. And all I need is 650. Any advice on how I can overcome my anxieties and to get a higher Quant score? Thanks so much for your help! It has been a long long journey.
