@ShawnO33 For the purposes of the MCAT, a distinction between the G1 and G1/S checkpoints aren’t made to my understanding. Based on what you shared in the Extra, G1 checkpoint would fit best into the Text since it focuses more on the choice of division compared to the G1/S checkpoint, which focuses on the transition. For the sake of brevity and what is necessary to answer questions on the MCAT (which is the litmus test we use for suggestions), we can keep the content in the original card. I understand this might be frustrating since you wrote at length in Extra about this. I just want to keep in mind what would be best for all users
