N@TM Review

NIght at the measuem was an amazing experiecne and I was able to let others see the project that the group made. I was also able to see other peoples projects! Some projects that I really enjoyed was; Ava's ASB merch website. Their website was able to keep track of stock and see how many in the stock are left. I also really enjoyed Edrick's calender page which shows what is up next in your schedule. Another amazing project was Tay's study quiz website where you are able to quiz yourself on the quizes you take and you are able to recive your score.
