Hi,
Hitting up to 48 is possible with your own maths skills.
When it comes to CAT, CAT scores tend be slightly higher than actual GMAT score, and it's better not to highly rely on CAT score. Contrary to 48, scores of 49-51 require another level of different math skills.
On GMAT Math, you should be strong at solving final hard 4-5 questions which are difficult to solve, in order to hit at least 49 or above. We call them CMT questions (Common Mistake Type). In fact, these hard 4-5 CMT questions are given on actual GMAT. If you get 1-2 questions wrong, you can definitely hit 49. Or, if you get 0-1 questions wrong, you can hit 50-51. So, you should get 3-4 right out of hardest 4-5 questions. These questions usually take 4-5 minutes to solve per question. This is a big pressure because we have to solve 37 questions in 75 minutes. However, with our unique Variable approach for DS and IVY approach for PS, you can easily tackle those difficult questions.

www.mathrevolution.comWe provide difficult questions on level of 700+ to our member if they need to push themselves further.
If you look for difficult questions of 700+, we can provide our CMT questions. Apart from CMT, focus on studying the key questions, 5 chapters (Integer, statistics, probability,inequality, absolute value), which completes 80% of your study for GMAT. In addition to the key questions, it is greatly helpful to study difficult questions as well.
Happy Studying!
