Need an advise for my Survey?

My Survey's topic was: Do Having Diff. Types of groups/peers affect A student's interest in Studying?





And I am Thinking If I can Ask Their grades in main Subjects.





I also need more questions to be added to the survey. Please help me!!





Thanks!

ask if the person is male or female then ask if they study with predominately a room full of boys or girls. you could also the economic status of one for example maybe "poorer children" don't have an interest in studying because they have more chores or responsibilities in order to keep the household going. try things with social status, economic status, after school activities such as sports or scouts, and so on.
