I found that not only did these Infographics help when it comes to revision for exams, but they are also notoriously effective for consolidating new learning. However, I find that the greatest value in these (for me) is making them, rather than reading from them. And as for the new learning, these tend to only supplement it, and require some previous knowledge to fully understand it. Thus, they are almost worthless at face value as a standalone.
This one, on the lac operon, was made a few days after the lesson on it was delivered to us.
