At the risk of stating the very obvious, this is what “lab exams” are for.   For you to figure out the solution for yourself.   For you to learn what resources are already available on the net and where to find them.   (Hint:   this isn’t the place.)   And for you to learn how to manage your time so that you are not racing around like a proverbial headless chicken at the proverbial eleventh hour.   Yes, sometimes a test teaches you most when you fail one.   Experience is the best teacher, but she teaches at the school of hard knocks.
