Hm.... If you’re taking it on site, you should get the scratch paper not the drawing pad....
Basically you get a physical scratch paper in the test center which is better than the drawing pad thing.
However, if your test center was not a positive experience, you can definitely take it at home. You just need to make sure that you don’t get any disruptions during the test and you can focus. You cannot wear headphones or earplugs at home.
They disadvantage with taking the test at online at home is that there is often a noticeable lag when clicking the next and submit buttons that affects most people in international locations. This would affect all of the sections whereas calculator affect only the data insights section.
The issues with school review that our routine should not be a problem for most since you’ll get the score and I just may take a bit of extra time to report it to schools but that is not a problem.
