Hello reneew1024,
Hard luck on your score on the GMAT.
What you experienced is not something out of the usual. A lot of test takers report having had such an experience on the actual GMAT, although they were scoring well on the mocks prior to the test. One of the major reasons for this, is nerves, due to this being the actual exam. Also, in a mock test, subconsciously, you know that even if you get some answers wrong, you can go back, review/retake the mock; whereas, in the actual test, you know that there's not even a way of figuring out if your answer is right or wrong. This just adds to the pressure.
Your Quant score seems to be fairly consistent, although with fewer mistakes, you could have hit a 50 which would have boosted your overall score as well. Focus on reducing the number of wrong answers, especially silly mistakes.
Your Verbal score suggests that you are falling for the trap answers quite frequently. This also means that, although you may be fairly confident in one of SC, RC or CR, there may be quite a few grey areas in the other two sections. Therefore, you are making mistakes in the medium and medium-hard level questions because of which your Verbal score has not risen up to a higher level at all.
It's a good idea to subscribe to the Enhanced Score Report (ESR) for your most recent attempt of the GMAT. The ESR will provide you with THE DATA that you need to analyse your performance objectively and then plan your approach for the retake. It's also a good idea to get your ESR analysed by a GMAT Expert who will be able to see through the data, since they know these numbers like the back of their hand. As such, they can give you sound advice on what you can do differently in your preparation for the retake.
Hope this helps!
Wish you all the best.
