Almost all resources on PrepLounge (that includes the case studies) can be used with freemium access which means that you get to try it to a certain degree but have to upgrade to Premium to use it to the full extent. However, you have free and unlimited access to the cases included in the free Basic Membership.
In our Case Library, you will find 200+ case studies for your case interview preparation. Solve challenging problems around market sizing, pricing, or sustainability.
