Quant is weird. If you are good at it, you just are. If you do not grow early into your preparation, however, quant can be very difficult to improve on no matter how many questions you solve. Here are three common problems that are most often ignored by students.
GMAT is extremely time intensive. Also, given the adaptive nature of the paper, you must get through the easier questions quickly to stand a chance with the tougher ones. That means you have to be both precise and very nimble with your calculations. When was the last time you worked on quick additions or multiplication though? High school, right? Exactly. Start mentally calculating difficult calculations. You don’t need an app or a tutor for that. Just sit, throw yourself random numbers, and check your accuracy and speed.
2. You know the syllabus but not the foundations it is built on.
The official guide outlines the chapters that are the core of GMAT quant. However, these chapters are built on simpler concepts. For example, Mixtures and Work Rate are built on the Unitary system. Sadly, few institutes would even introduce this idea as part of the syllabus. Pick up a foundational book from your boards exams and revise these basics. You will find that you feel much more confident with the paper.
3. You find it difficult to mix concepts.
This is for those looking to get a 49 or above in quant. As you get your questions right, the GMAT increases the difficulty of questions. It does so by mixing chapters. For example, a speed distance question that relies on your understanding of co-ordinate geometry to figure out the path taken. If you have only been practicing ‘question types’ , you will find this intuitive jump nearly impossible to make. So, make sure you learn the premises of each topic and build an understanding of the logic to maths. Do NOT try to pick up formulas for different question types if you are aiming higher than a 650.
