Can you help me go from a 620 to a 650?

I think if you take some prep course you can reach the 650 level without problems. You can improve your quant score up to 47-48 level.

Good luck :D

I think the Quant section is unique in the GMAT in that ir has DS type questions. I think you need to isolate your weaknesses in these CATs and understand where your mistakes. Are you weaker with inequalities/statistics/geometry type questions for example? or is the DS questions that are troubling you? Then you need to focus on the theory or how to tackle these types of questions. You can purchase question packs or practice on the forum for example.

Hey kpadge92
You're score is already good, and you need a bit of a push to climb over the hump.
The way I see, there are three kinds of possible improvement that can be relevant for you:
- Professional improvement: as in, you just don't know some of the material well enough yet. Perhaps this is the casein Quant. Ask yourself: are some of your mistakes here coming from simply not being sure what a formula or rule is? If so, go over the relevant material. Ie don’t recommend starting by tackling the hard questions directly; this is like treating the symptoms only. Getting to understand the material well treats the condition.
- Strategic Improvement: This could be relevant if the trouble you're having with the practice tests has to do with not having enough time? If so, this entails examining your entire approach towards solving the different sections, and thinking of ways to optimize your results. A prime example of this is figuring out how to plan your time for each section: how much time should you give an average question? Should you divide your time evenly, or plan for less time on easy questions and more on hard ones? Since the GMAT is an adaptive test that uses your first few questions to establish your level, should you give the first 10 questions more time?
If you see there isn’t enough time in a certain section, you should figure out beforehand how many questions you plan to solve and how many you’ll guess.

- Fine-Tuning: this is the easiest route, and thus may be the most cost effective. Are you making mistakes that don’t derive from lack of knowledge, but from simple lapses in concentration? If so, there may be some simple fixes you can make to your question-solving system, which may make a big difference.
The main rule of thumb you must remember is that the fewer details you have to remember, the freer your mind is to actually think. For this reason, we recommend writing down as much as possible: maybe it will help you to write down a few pesky formulas right at the start of the test section. Maybe for questions with lots of confusing wording you’ll benefit from writing down a short summary. Maybe by the time you go over all the answers, you forget which ones are right and wrong,and it’ll help you to write down the letters A-E and cross out each one as you eliminate it in your head.

Hope this helps.

Hi kpadge92,

GMAT Math is logic math test, rather than math skill test. That's why students majoring in engineering or math have hard time in improving math scores. You should learn 'logic' to solve GMAT math. Since you have an engineering background, we assume that your basic skills are better than average students.

​W​e highly recommend learning our approaches. Since it takes about ​76​ hours ​(2400 questions) ​to complete our course​ ​(All-In-One 51), you will surely hit your target score by learning our approaches.​ ​

With our unique approaches of Variable approach for DS and IVY approach for PS, you can significantly save time, and will have 10 minutes to spare on exam. For instance, with our approaches, you can solve questions that normally take 4 minutes in 1 minutes and 30 seconds, and 2-minute question in 30 seconds.
Also, You can solve DS questions 100% with Variable approach and 30-40% of PS questions with IVY approach.

If you would like to try our approaches, Please try Trial Pack (4 hour lesson) that reveal our secret approaches of DS+PS core theory that you have never seen. You can test whether you like them or not before you enroll.

Additionally, the below is a useful article featured in GMAT Club for your reference. This will be helpful for you. You can see what sort of questions you might encounter on actual GMAT.
