When opening an AWS account simply select a normal/standard account with the 'Basic' (zero cost) support level. You can upgrade to a paid support plan at any time. However, for the purpose of our training, it should not be necessary.
Here is a link to Amazon's pricing for the different support levels.
The Free Tier rebates will be applied by AWS automatically to any qualifying resources you have used
* Note that the "Free Tier" rebate is not related to the support plans. (Hint: you may be asked about this on the exam) *
