How To Apply - Application Forms

With the application forms below you can register for the course. You may choose to start at any time, the course account access will be provided to you upon receivement of the course fee.

  • Computer Requirements

    The course is web-based, meaning the course does not need to be installed on a local PC, but it can be accessed from anywhere in the world using a web-browser. Some parts of the theory require a flash-player. These are common and can be downloaded for free.


In the current learning age, content cannot be seen separate from technology. The SOWISO Digital Calculus Course offers the best from both worlds. The Course provides a true personalized learning experience for a fraction of the price of a regular textbook.

Correcting homework and (practice) tests is not necessary anymore. Intelligent feedback helps students where they need it. This course provides real personalised learning, even with large groups.

What is meant by 'open answers'?

Open answers in this course are for example calculations, or algebraic expressions. We have a user friendly editor to input the mathematics. (Have a look at the demo!) Apart from this, the course also contains Multiple-Choice and graphical/geometrical questions.

What is this 'Customization' and 'Targeted feedback'?

The software is not only able to see that a mistake is made, but also what that mistake is. The student then receives fitting feedback and tips, so they can continue the learning process with this extra useful information.

Does the course also contain tests?

Yes, for every chapter there is a diagnostic and concluding test on that chapter. The chapters also contain a lot of random practice exercises, which can be made over and over again.

How does this course relate to a MOOC?

A MOOC mostly contains theory, for example as video-lectures. This course mostly contains interactive elements, like exercises and tests, which provide you with feedback on those subjects where needed. This is something a traditional MOOC can never offer.

What kind of hardware do you need?

The course is 'in the cloud'. Meaning, you only need a computer or tablet with internet connection.

What is the price of this course?

The price is 1500 INR per account per year. A fraction of the price of regular textbooks.

Are there other Digital Math Courses available?

Yes, there are more SOWISO Digital Math Courses available. Drop us a line if you want to know more about Digital Calculus, Digital Linear Algebra or Digital Statistics.

Other questions or live demo?

If you have any other questions or need an extensive live demo at your university, please drop us a line.

Can I print out parts of the course?

Yes, a simple click will provide an instance of each chapter, theory page or exercise. We refer to an instance as many exercises are driven by paramters which are set randomly each time the text is rendered, so two instances are very unlikely to be the exact same.

Letter to Students

Dear Students and my Friends,

Let me welcome you to this introduction to an entirely new way of learning. I can guess this new way is making you curious. I am assuming that you are either a XIth or XIIth standard student and even if you are not, I encourage you to read this because someday in your life you will encounter this phase of which I am going to talk about now. The phase of extreme competition. The phase where you are trying to get into an engineering or medical college. The phase where peer pressure is high, parents expectations are mounting and you only have two years to prepare for a big list of roughly 100 topics spread across mathematics, physics and chemistry (for engineering) and biology, physics and chemistry(for medical). I know what you must be thinking: Should I apply for a specialized coaching if they are 10 times more expensive than your school fees. Should I go to my parents and ask them for the money. Should I find an expert tutor nearby? I know these answers are not easy. And you will be under heavy stress of where you should go, who you should talk and many more things. We (SOWISO and Riyaaz) have worked out a solution for you. What you need is only two things: First your passion to learn and second a very minimal internet bandwidth. [That means if you can open Google and it is working, that is enough.]

We brought for you an innovative textbook on Calculus, a digital textbook offering a truly personalized learning experience. Of the roughly100 topics I mentioned above Calculus is just one topic. So you must be thinking how it helps you. You must be thinking what about those other 99 and how am I supposed to prepare for that. Let me give you an answer to this. Yes, it is just one topic of this entire list but of your two years you will not have more than 20 days to prepare for it. And if you don't get it in those 20 days, you won't get it in two years. Because there is no place you can go back and revise your concepts. And thing is: if you don't get Calculus right you lost half of the battle already because Calculus is used roughly in every chapter you will read in Physics. So it is very important that you get a specialized training in Calculus as a complimentary to your preparation for exams. Trust my words, this is must.

You must be wondering about me. Who am I? Why am I so confident of what I am saying? Well let me tell you that I am just like you! I am one of those who went through this phase and I was amongst those lucky ones: Who could crack an IIT exam and got into BITS. And I am sharing this with you because I don't want you to wander in dark for what you should do. This is where we (SOWISO and Riyaaz) brought this amazing learning platform for you. I guess you are now thinking about price. So let me give you good news. It is just 1500 INR per course. For the specialized coaching in India you pay a minimum of 50000 INR today. So how can we charge so less? The reason for this is very simple: It is not about the money, it is about YOU! And that you should pay for what you desire. But before you pay, the very first thing that matters to us is your engagement. That is why we offer you a demo first. We look forward to hear from you.
