Columbia Science Honors Program

It would be really helpful if anyone could answers these questions! I am currently applying for the SHP program and my admission test in next week and I was wondering if the test is really hard? What type of science and math questions are there? Do they provide calculator and scrap paper? and for people who are already in the the program is it worth it? like do you enjoy the classes and learn something? I know i’m asking a lot it’s just that i’m super nervous for this and thank you in advance
