text: One important reason why summer projects should be teacher-designed is because it helps students focus on the more important topics. Teachers can see if you have any weaknesses on the subjects you need to remember the most and he/she can help you improve in that catagory. Also, students may do their project on things totally off topic from what was taught in class if they design it themselves. These teacher-designed projects may also help you learn even more about the things you've learned. Extra learning on things you're already skilled in only makes you better.
