What Our Students Say About the Complete Journey

"Buying the complete companion was the best decision I made. Every time I had a question about the next step, the answer was right there in the course. It took me from a complete novice to confidently building my own walls." - Prof. Krishnaswamy Raghavan -  Renewable Energy - I.I.T., Kanpur

Frequently Asked Questions

• Is it cheaper to buy this bundle than to buy the parts separately? Yes. The Complete Companion bundle is offered at a significant discount compared to purchasing all four parts individually. It is the most cost-effective way to get the complete syllabus.
• Do I need to complete the parts in order (1, 2, 3, 4)? We highly recommend it. The curriculum is designed to build upon itself, with materials knowledge being foundational to everything else. However, with lifetime access, you are free to jump to any section you wish.
• How long will it take me to finish the entire 30+ hour course? This is entirely up to you. As a self-paced course, you can move as quickly or as slowly as you like. Some students binge-watch over a few weeks, while others take several months to absorb the information alongside their own projects.
