Have you talked with your tutor about your problems?
It is normal that the school either supplies enough information to be able to complete the project, or that the school helps with what information to search for.
The level of the assignments are adjusted to the expected knowledge levels of the students, i.e. the assignment is just a bit harder, to require the student to not just sail through the assignment but to actually have to spend a bit of time thinking. But the assignments are not so hard that the students are expected to fail, if they do try.
