a📀 bruh if ur struggling or if u dont know a formula just list them
odd numbers:
181, 191, skip 200-300, 10 for 300-400, skip 400 onward
total is 2 + 10 = 12
all numbers:
181, 191, 10 for 200-300, 10 for 300-400, 404, 414, 424, 434, 444, 454
total is 2 + 10 + 10 + 6 or 28
if im being honest you should be able to gauge how long a question should take you and whether or not its "worth" the mark, id probably just skip it
