Please read the comment once again Sir.

And if you still find it difficult then you can attempt the theoretical one. You have both options available.

Please do note that practical tasks cut across the loosely defined thing of theoretical concepts. The idea of the crypto academy is not about the rewards primarily, nether it is a number game of labels Beginner[1,2,3,....,10]. At the end of the day, the real value of the Academy is how many users are getting familiar with the real use-cases with real transactions.

Still, the Beginner tier fixed is not hardwired to practical task only, it's a combination of both.

I would repeat again-- You have both options available[Practical as well as theoretical, it is up to the participant which one to attempt]. Let that sink in.

Thank you.
