  • If my district subscribed, I’d definitely use Sero! | I’ve not seen anything like this. | Ingenious. As cool as I thought it would be. | Nifty - better holistic way to do assessment.

  • I liked it. I haven’t seen anything like this format. Usually just paper and pencil. I’d like to use it as an education officer. I can see this being really useful for testing someone’s knowledge. But as a learner, I’d probably do better on a Multiple Choice.

  • I just wanted to give some feedback on the concept map program! I really loved the program and thought it was easy to use and very self-explanatory. I think future students would have no problem figuring out the program, especially after the first time working through a map.
