Questions

Here are some of the questions we get all the time. Don’t see your question? No problem, just send us an email.

Our system is very transparent. Signing up is completely free, you don’t need a credit card to get started. Once you have an account, you’ll unlock all our concept questions and get instant access to calculator solutions for chapters 1-4 of any book that we have available. This way you can try us out and see if we’re a good fit for you, completely risk-free.

Some of our more advanced math-based calculators from later chapters may require credits to unlock. You can purchase credits as needed and then use your credits to unlock our premium calculators, similar to an arcade. You are in full control of how many credits to purchase and use, and there are no recurring fees or hidden charges. We are a no-nonsense business, period.

The best way to answer that is to take us for a spin. First, sign up for free and save your textbook(s) to your favorites list. Then after clicking on your book, simply search for your homework problems within your book using the search bar. Then simply unlock the calculator and input your numbers.

Our system is much more equitable than paying month after month for a service you don’t use all the time. We are NOT yet another subscription you forget to cancel! Try us out for free, and then simply add credits to your account when you need them. Simple.

CourseStar is fair. Not all calculators are created equal, some required a lot more time and effort to create by our staff, and thus the cost of those calculators reflects that. For this reason, very lengthy problems, or questions that require more advanced mathematics behind the scenes, use more credits than the easier problems, most of which are free. Extremely difficult problems will be marked HARD.
