This is not a course for AWS beginners.

Hello @hungng777
Sorry for the inconvenience you have experienced. Our team have tried their best to provide as much detail as possible in the lab introductions to guide the students through the labs. However, if you have any particular issues with each one of the labs, you can tell us, and we will try to add more information to make the labs easier.
I’m finding this week 1 lab ( Practice Lab 2: Interacting With Amazon DynamoDB NoSQL Database) confusing and agree with the original poster. This lab expects users to know lot of DynamoDB and to externally read up on the AWS links while we have a limited amount of time with the lab. The links to the AWS documentation can be overwhelming and not very clear.
I felt rushed to get this lab down due time limit but it’s hard to understand everything that is going on without having some background in DynamoDB.
The markup denoting what is “None” : “None” is confusing in some of the exercises. I didn’t know if i had to change both by trial and error.
Exercise 6 hints are vague in terms of limit. Do we just put any integer to limit? The hints implies a limit but i don’t know if it’s just some arbitrary number. You should update hints to tell users any integer range is ok or something. The response JSON formatting is hard to read without a better formatting.
Exercise 7 just has no hints and is not clear if the steps of Exercise 6 applies to this. I had to guess this was the case. I suggest adding hints for people not understanding the table formats.
Exercise 8 has vague details again on how the expected name. The naming conventions in this lab is confusing on what you need to pass. I had to look at the optional sections to figure out how to get the expected format.
Exercise 9 - same above. If you didn’t figure out how to do exercise 8 you are kind of stuck here.
I finished the lab but it seems to much to absorb for a beginner course.
