Target setting reflection

the purpose of setting target's for the various subject is because you can achieve your target each term and improve the next term/year.I think the target setting is useful because if you plan your target you can achieve your target by studying hard.I
set a low target for 1-2 of my subject because i am bad at that subject.I am studying hard to achieve my target,i don't have a plan so i just keep studying.
my parent's are helping my achieve my target by giving more tuition time and more work to do.I don't know what to do to motivate myself towards my target.My teacher could give me less homework so that i can study more at home.
