Ive been working on an assignment for the whole day and my sister keeps on making me write more than I should and keeps on pushing me to add extra stuff that is unnecessary. I already know that most of my classmates write 2 sentences most of the time and its usually not a problem but this particular assignment has a lot of questions and she expects me to write like 2 paragraphs for each of them. And since I've been working on it since morning and its now 7:12pm I cannot think like at all. Can anybody tell me why?

She probably enjoys language and writing assignments.  Or maybe her teachers make her write long answers on hers.  You can try reasoning with her and telling her that you have different ways of doing things like homework.  There is a time for essays and a time for one-liners.  It isn't her grade after all.

Explanation:

either online or traditional classroom can work for students. which is better will depend on students and teacher. students may have trouble following a lesson in classroom while they can study at their own pace online. other students may have trouble staying focus on their own in online classes. teachers are more used to classroom teaching but they may also be more worry about their jobs teaching online classes and work harder.
