Answer 2

Nope, sorry. Education, and philosophy in particular are about exercising your own intellect. It's what your teacher expects of you. If you're unwilling or unable to do or understand the work, I suggest that you drop the course and take up something less demanding. 

Answer 3

Pleasure good, pain bad.

Mill's simple/simplistic axiom:  people know what's happy-making.  E.g., Jews are bad, because they take work away from Germans (inferior monkeys somehow doing better).  So, it is good and of high utility to place Jews in slave labor camps, to serve the superior group (non-Jewish Germans clearly have higher-level pleasures of contemplation).

Trolley:  always sacrifice your unhappy-making enemy. If you're a Jew, and forced to choose by a philosophy professor, saving one Jewish life may be better (happier) than saving five Gentiles...or perhaps saving five students is better (happier) than saving one philosophy professor.

Fat Albert:  you like children, and "think," like Dr. Ezekiel Emanuel, that Fat Albert has a lower "quality of life" (fat, black, looks elderly), so murder the character.  https://townhall.com/tipsheet/cortneyobrien/2020/1...

Kindly note that the fat man example presumes you have the authority to murder to save others... ~ = PRC treatment of Uyghurs, Soviet treatment of Ukrainians, etc., etc.
