What to Look Out for in an Online Math Course?

Remember this! When choosing an online math course, there are several factors to consider to ensure it meets your needs.

Firstly, think about your preferred learning style. Do you like video lectures, or do you choose practical exercises? Some courses provide a variety of practice materials, such as flashcards, quizzes, and assignments, while others focus more on theoretical concepts.

Next, consider the price. Some courses are FREE, while others may require a subscription or a one-time purchase. Think about your budget and what you’re willing to invest in your learning.

Teacher qualifications and approach are crucial, especially in a challenging subject like math. Look for a motivating teacher whose methods align with your learning preferences.

Consider the teacher’s style and level of qualifications – a university professor may have a different approach than someone with a diploma. 

Consider how specific you want the course to be. Are you interested in a particular area of math, or do you prefer a more general approach to the subject? Ask yourself these questions to design your choice according to your specific interests.

Lastly, think about your goals for the course. Are you looking to expand your knowledge casually, or are you considering a career path related to math? Your goals will help you choose a course that aligns with your desired outcomes. It’s as SIMPLE as that!


I’ll come to the point directly.

Some courses which I’ve discussed, such as those from Khan Academy, are FREE. Also, if you don’t need certification, three Coursera courses on Mathematical Thinking, Statistics, and Calculus are free. However, if you want a certification, the upgrade fee is usually about $50.

Plus, for individually paid courses on platforms like Udemy, the typical cost is around $50. Udemy often has sales, and if you’re new, you might get a good discount on your first course.

Coursera specializations, like Johns Hopkins University’s Algebra Specialization, are paid monthly. The faster you finish, the less you pay. However, remember to cancel your payment when you’re done.

Some courses come with a subscription. With platforms like MasterClass or Brilliant, a subscription grants you access to all classes. This is a good choice if you’re uncertain about committing to just one area of interest.

A MasterClass subscription costs $11.80 per month (billed annually), and a Brilliant subscription is $3.78 per month (billed annually).

Note: Platforms can change their pricing details to keep them up to date. So, it’s ALWAYS BEST to check their website before you enroll for a course.

How Long Does it Take to Learn Math?

an image of math stuffs and laptop

The time it takes to learn math depends on your goals. 

If you want a deep understanding of a career in math, longer courses spanning weeks to months or even years may be necessary. These provide a comprehensive grasp of fundamental concepts.

On the other hand, if you want to refresh or focus on specific areas like statistics, shorter courses (a couple of weeks) can be sufficient. They offer targeted learning with ample time for practice through assignments. 

However, Remember! Math is extensive, and people can spend a lifetime studying its various aspects. Set clear goals to design your learning approach accordingly.
