I'll just tip in a few words while waiting for the person you asked the question to give answers. As a student in a class, lecturers usually give assignments sometimes based on what they've taught or something different for the class to make researches.

• The lecturer has the right to specify that he wants the assignments to be based on his pattern of teaching or solving if it's a mathematical problem

• Most students do research on different ways to solve a problem easily without following the teacher's example or may want to impress the teacher by being outstanding. In such a case, the teacher having a wide range of knowledge on how problems can be solved from different angles, should evaluate the assignments of students from different approaches as there no one way to solve something. In as much as the questions uses an accurate step with good result or answer, the lecturer has the right to pass the students not necessarily based on his own steps unless specified.

• I feel since we belong to different regions and we have different ways of doing things, there's should be a specification to the tutorials given. You can mandate us to work based on your own style so we learn your pattern of drafting clothes of different styles. I think this will work best as the first user who participated thought doing it the way she understood will work better for her though she disregarded a rule.

In conclusion, I think there should be a specification that we should work based on your format. My little contribution. I mean no harm.
