None of the experiments will repeat per subscription. For example, if you joined the STEM Lab Deluxe for 1 - 24 months, you will never repeat an experiment. The same is true for STEM Lab and STEM Snack. However, there may be repeats between STEM Lab Deluxe, STEM Lab and STEM Snack. We are trying to avoid duplication, but we cannot guarantee this will not happen.
