how to get faster

[cksghdrla2]

i usually get to high 60s or low 70s with skipping some stuff
and i must get faster
how?
i think i spend alot of time in estimations, cuz i don estimate, i actually do the math kinda..
and some help in tricks needed
1)1234/9 (mixed number)
i just do them, is there trick?
2)95634/278 it's an estimation, whenever i have division, i always actually do them, any faster way?
3)33 ft/s = ________mph
how do u convert from ft/s to mph fast? any general formula?
thx

1) I would say just doing them is fine. If you want a pattern, [unparseable or potentially dangerous latex formula]

So, for [unparseable or potentially dangerous latex formula], you divide the [unparseable or potentially dangerous latex formula]th triangular number by [unparseable or potentially dangerous latex formula]. Turn to a mixed number and write the fraction part down... add the [unparseable or potentially dangerous latex formula]st triangular number to the remainder and write that down (carrying the tens) and so on until you reach [unparseable or potentially dangerous latex formula].

2) I think a key tactic to learn in estimating is to try to get close and know if you're above or below. Then, you can be generous in compensating for error. Estimations are much different than the rest of the test. Maybe you can practice sheets of estimation problems. Personally, I mostly skipped the hard stars.

For [unparseable or potentially dangerous latex formula], I'd say [unparseable or potentially dangerous latex formula]. That's a small enough change that you shouldn't worry whether it encourages positive or negative error. Division by [unparseable or potentially dangerous latex formula] shouldn't be hard. Put down a couple digits and then [unparseable or potentially dangerous latex formula]'s. On the second digit you write, don't do any exact calculations. Just guess about how many times [unparseable or potentially dangerous latex formula] will divide [unparseable or potentially dangerous latex formula].

3) Multiply by [unparseable or potentially dangerous latex formula]. Memorize the fraction. The hard part is remembering which way is which. After enough of these, it's easier to remember that ft/s is always the larger number. At first, maybe remember [unparseable or potentially dangerous latex formula].

if u want to get faster, just practice more tests. theres really nothing else to it. other than learning the trix of course.

also i was wondering. how far back should i go to practice? eventually around 2000ish, the trix are kinda outdated right?
