in grADE 8 IN any instrument, you only need to do max grade 4 theory in ameb. it actually ain't that bad cuz its just cadences and 4 voice melodies that are a bit challenging
first one, i recommend doing them only if it's related to chemistry (like atoms or the periodic table) cuz it might help. don't draw like anime characters, they're a bit of a distraction (underestimation)
second one, no one cares, keep doing what u did. same with the 4th one. if its clear for u...
based on what i've learnt (which is not the most lets be honest), yes it pretty much is just actual length of scale bar divided by the measured length of scale bar and then multiplied by the measured size of the cell
yea that's a good idea
but i feel like u guys making questions up on the spot will be more fun
and besides half of tshc don't have a lot of half-yearlys and my school never gives past papers that easily (until a week before the test)
for a, it's velocity of the cyclist divided by the constant acceleration of the bus
for b, use simultaneous equations
for c, use the answer u get for b i think
