75% of American high school students are not good at mathematics and science because they need to attend high school in the United States through 4 years of mathematics and 2 years of science. Students will study one or three exams each day in mathematical subjects, weekly scientific subjects, monthly quizzes, and semester. Even in front of the university it is six years. It is running in the public beta (I launched the Android version yesterday!) It is growing and there are thousands of experts in an hour trying to prove us to all in the continent Thousands There is sometimes a moment "Oh". There are twists around here, but we have learned a lot: we will expand soon

Then the world does not change much. I would like to avoid hard work such as preparing math homework and scoring mathematical tasks. As you know, the teacher wants individual students to help and I think that this is not another skill set. After all, as the Department of Education becomes very popular it will expose people to these new learning models. So you are ready to accept these things. There may be generations of teachers who do not use these things. But of course young teachers came and they chose to receive education, and they knew this was part of it. For the K - 12 teacher, that is to eliminate mainly what they do not want.

There is a mathematics class where the teacher assigns homework of 1 to 2 hours every night. This is irritated. I got crazy until I noticed that these homework tasks accounted for only 10% of my final academic year. From that day, when I thought that they helped me learn something, I did my homework only. My grades are close to the whole class, and I do not have much time to do my homework.

Kwyk is an online learning platform that allows students to learn their homework online. For students aged 11 to 18, assignments by teachers on the platform are assigned. Everyone has various jobs that are automatically generated, but the difficulty of all problems is the same. For example, 1/3 + 1/2 is almost the same as 2/3 + 1/4. As a result of homework generation students can retry at any time to get the best grades in the new version of the assignment. They can also freely address any particular chapter at any time. For fairness, 90% of the activity is assigned by the teacher.
