For my exam yesterday the first question was where u had to measure the length height and width of a rectangle and find the volume. I measured it correctly and got 5.2, 3.1 and 3.2 etc. The next question was to find the volume using the formula lxwxh and I got 31.232 but I thought I had to round to two sf from the previous answers so I js rounded it to 31. There were many follow up questions where I had to use this number and wondering if I can get ecf marks and still score full marks cause I showed my working for everything and how I rounded it to.

So I haven't even touched the business book at all and never did well in school or studied. I kept on procrastinating my self till now. And now I have literally 10 hours till my exam starts. Please I need to get a c or below. If u have any notes or tips please help me. Im so cooked I wanna cry
