Quant skill is quite a broad definition. Let's split into the following:

1) Fast math - train, train and train again

  • Learn how to multiply double digit numbers (google fast math tips)
  • Learn the division table up to 1/11 (i.e. 5/6 = 83.3)
  • Learn how to work with zeros (Hint: 4000000 = 4*10ˆ6)
  • Use math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

2) Critical reasoning

  • GMAT test CR and IR parts (Official guide and Manhattan prep)
  • Mckinsey practice tests
  • PST like tests from the web

3) Working with tables and graphs and deriving conclusions

  • Study "Say it with Charts" book
  • Check all available MBB presentations and publications. Practice to derive conclusions and check yourself with the actual ones from the article / presentation
  • GMAT IR part (Official guide and Manhattan prep)
  • Learn basic statistics (Any GMAT or MBA prep guides)

4) Case math

  • Practice common market sizing topics (Airport passenger flow, real estate volumes, subway passenger flows, car usage, etc.). You should become comfortable with making assumptions
  • Learn key financial topics (P&L and balance sheet and how to analyze them, Basic Valuation principles via NPV and comps) and case tips (e.g. Rule of 72, Perpetuity)

Good luck!

Hey, in addition to consulting-specific math practice, your best bet is to actually get some GMAT math practice materials and work on those. There are plenty of resources online and countless practice problems you can check out. Since calculators are not allowed on the GMAT and since the GMAT primarily tests your ability to think logically rather than any advanced mathematical concepts beyond high school algebra (you won't be doing calculus in any case interview), these questions will really help boost your math/quantitative skills

Improving quantitative skills involves practice, understanding core concepts, and approaching problems methodically. Here are effective ways to enhance your quantitative skills:

Understand Fundamentals:

  • Ensure you have a strong grasp of basic mathematical concepts including arithmetic, algebra, geometry, and statistics. Without a solid foundation, it's challenging to tackle more complex problems.
  • If you are studying a specific field like finance or physics, understand the mathematical principles relevant to that area.

Practice Regularly:

  • Practice is essential. Solve math problems, work on puzzles, and engage in quantitative activities regularly. Websites like Khan Academy, Coursera, and edX offer free math courses at various levels.
  • Use math apps and games designed to improve mathematical skills .

Online Courses and Tutorials:

  • Enroll in online courses on specifically designed to improve quantitative skills. Websites like Coursera, edX, and Udacity offer courses in mathematics, statistics, and data analysis.
  • YouTube has numerous channels dedicated to teaching mathematics. Find educators who explain concepts clearly and work through problems step by step.

Textbooks and Workbooks:

  • Use textbooks and workbooks designed for various levels of math proficiency. These often contain a structured series of problems ranging from easy to difficult.
  • Work through problems in areas you find challenging. Understanding the solution process is crucial.

Mathematical Software and Tools:

  • Familiarize yourself with mathematical software like MATLAB, R, or Python with libraries like NumPy and SciPy. These tools are widely used in various quantitative fields and can help you visualize problems and solutions.
  • Spreadsheet software like Microsoft Excel or Google Sheets can also be used for quantitative analysis. Learn to use functions and formulas for calculations.

Critical Thinking and Problem Solving:

  • Develop your critical thinking skills. Understand the problem before trying to solve it. Break it down into smaller parts and identify the mathematical concepts needed to solve each part.
  • Practice solving real-world problems. Understanding how to apply quantitative skills to real situations is invaluable.

Collaborative Learning:

  • Join study groups or online forums where you can discuss mathematical problems with peers. Explaining problems to others can deepen your understanding.
  • Participate in math-related forums or communities where you can ask questions and learn from others.

Seek Guidance:

  • If you are struggling with specific concepts, consider hiring a tutor. A one-on-one session can provide personalized guidance.
  • Don’t hesitate to ask questions in your classes or online. There are plenty of communities where people are willing to help.

Stay Persistent and Patient:

  • Improving quantitative skills takes time and persistence. Don’t get discouraged by challenges; instead, view them as opportunities to learn and improve.
  • Practice regularly, and with time, you will notice significant improvements in your quantitative abilities.

Remember, consistent practice, a curious mindset, and a willingness to learn are key factors in improving your quantitative skills. Tailor your approach to your specific needs and goals.

Dear A,

GMAT is a good way to practice you quantitative skills. Any handbooks, giudelines or test simulation would be helpful. Just practice.
