High-quality, colourful, easy-to-read summaries on the following areas: the cardiac cycle, respiration reactions, the nitrogen cycle, the humoral response, and primary succession. Useful for visual learners, like me. It's a bit of a random selection of topics, but these were the ones my class and I found useful :)
