Hi,
Asawa7GMAT quant is not just composed of pure math questions but logics. If you are a beginner, it could be difficult to solve those logic questions. The most important thing to improve your score is to be familiarized with those question type and solidify the basic concepts. Also, you should keep in mind that there also exist sequence and strategy to be a master of quant.
Focus on DS first. DS can be a quick win. If you master DS, it will be easier and less time consuming to tackle PS problems. There are patterns and logic to GMAT quant problems and you can save a lot of time especially in DS questions. With Math Revolution ’s ’Variable Approach’ for DS questions, you can minimize time spent on each question while improving accuracy (over 80 percent) (solving a question in + having a checking time = 2 minute) On average, our students have about 10 minutes to spare before the exam ends. To briefly explain our ’variable approach’, we apply ’variables–equations matching system’ to the DS questions. For example, you first need to count the number of variables and equations given in the question. By doing so, you can determine which answer choice will most likely be the answer. If there are only two variables in a question, you need at least 2 equations to solve the question. Since two conditions in the question usually give 2 separate equations, it is most likely that C (both conditions together are sufficient) will be the answer.
Then, you can apply our ‘IVY approach’ to PS type questions. Our IVY approach for PS focuses on translation of the question words. All the PS questions can be translated into mathematical formula. By applying ‘IVY axiom’, you can quickly solve the questions and have 10 minutes to spare. (More information about our approach:

I see where you're going with the 'Variable Approach,' and it is slightly terrifying me. Consider this question:
Company ABC manufactures only pens and pencils. Yesterday, Company ABC sold X pens and Y pencils. How many pens and how many pencils did Company ABC sell yesterday?
1) 21x+23y=130
2) 42x+26y=260
I purposefully made it obvious that C is not the answer, but on a less-obvious question of a similar type, the variable approach would lead a test-taker to fall for the C trap.
What are your thoughts on these traps?
