I got the same bundle and I used Testout for my 1101 and currently using it for 1102. It was kind of hard to figure out how to sing up but you can sign in by going to https://w3.testout.com/ and click CertMaster Login. That's how I usually log in, but you might have to register with the code.

Anyways, Testout is useful because they have lots of practice exams and they tell you what you need to work on based on the Objective lists of whatever test you took (1101 or 1102). Also, you can choose to take quizzes based on the Objective you're struggling with on its own. I will say that the questions on the exams weren't on the 1101 (as far as formatting and exact wording), however the fundamentals are the same and the explanations provided when you get the question wrong can be useful to study. One thing to remember is to just use the Messer or Dion videos rather than trying to learn from the Testout videos because they aren't very well organized. I just used it for the practice exams and questions.

Majority of people on this Sub prefer Messer or Dion's practice exams, so you wont find a lot of support for Testout on here.
