A: The preference is to make the plan for your master's thesis. So you use your spring project as a pre-study for your master's thesis, where through literature study or experiments you get deeper knowledge about the problem and have a better idea what to do in your thesis. But you can also make the plan for your autumn project, or for the combination of autumn project and thesis. You can also choose another project, but in this case please talk to the teacher. The idea is that you create a realistic plan for a realistic research project.
