In the beginning inventory, 5,000 units were 40 percent complete with respect to materials. During the period, 40,000 units were transferred out. Ending inventory consisted of 7,000 units that were 70 percent complete with respect to materials. How many units were started and completed during the period?.

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
