Yes. If your subscription lapses at any time, all of your progress and data will remain saved! In fact, this represents the core philosophy of our teaching approach. Our objective is to provide you with a single source review which tracks your performance over time. Our power analytics scores your performance on the direct review questions as well as multiple choice questions on each topic and subtopic. This analysis is continually updated and reported as your memory retention changes over time. When you re-subscribe to Firecracker, you'll be able to build off the same progress and data that you've accumulated, even after taking a break. Renewing Firecracker members are always eligible for excellent discounted rates as well; reach out to email@example.com and we'll hook you up with a great deal!
