Frequently Asked Questions
Is the free tier genuinely useful?
Absolutely. Every topic page, every diagram, every case study outline, and every quiz is available for free. The free tier alone is more comprehensive than most paid system design courses. Premium adds practice tools and personalized features.
What's included in a case study on the free tier?
Free case studies include the full problem statement, all 6 steps (clarifying questions, requirements, capacity estimation, high-level design, deep dives, trade-offs), architecture diagrams, common mistakes, and concept tags. Premium adds video walkthroughs, mock interview mode, and detailed solution implementations.
Can I cancel Premium anytime?
Yes. Cancel anytime with one click. No cancellation fees, no questions asked. Your content access reverts to the free tier at the end of your billing period.
Do you offer student discounts?
Yes! Students with a valid .edu email get 50% off Premium. Email us at students@systemdesign.guru with your .edu address.
What if I'm not satisfied?
We offer a 30-day money-back guarantee on all paid plans. If Premium doesn't help you, we'll refund you in full.
