hahaah Guys this thread is about approaching maths hw questions, not this "MIF is awesome" bullshit.
Anyways OP, like you said it gets tedious getting all of the questions done, usually I only pick out some of the questions from the questions to practice, enough for me to understand the concepts taught, but not so much that I get sick of it.(Mind you my teacher doesn't bother checking).
Once you get the knack of it, start practicing the past HSC/trial questions of the same topic to enhance your problem solving and familiarising yourself with the higher levels.
