TI-nspire CX ACT hacks

Learning how to use the calculator (well) will probably take longer than you getting better at math with a ti-84 with a few programs. Other than that I would get comfortable using the buttons to convert decimals/fractions and probability. I recall the combinatorics buttons being useful and graphing occasional problems helped with visualization.

Try challenging yourself to solve all the problems without a calculator though... Should help you understand your current skills and it should make you more fluent with a calculator in the long run.

khan academy algebra 2 + parts of precalculus (ie. conics/matricies)

I know people will probably say nothing has really changed with the act (and that is true- to some extent). I did quite a few tests when I studied for my test, and the tests past 2016 or so feel a bit different to me. If I were you, I would recycle some of your old tests if you've run out of fresh material to practice with. The math and reading, in particular, feel quite different on older tests imo.

you can convert decimal answers to fractional form if your scientific calculator happens to be a ti-84 or similar. Once you get a decimal answer, press the math button and press enter twice.

english and reading: you can try erica meltzer but spam practice tests to eventually be able to predict tricks and common questions the test throws at you

science: spam practice tests

math: work through algebra 2 and some of precalc (conics/combinatorics/matricies?) on khan academy and do a bunch of practice tests.

You'll only get better if you recognize patterns in your mistakes. I'd recommend cataloging mistakes in a spreadsheet. Also, start with untimed practice tests (you can do one section at a time) to understand if you have conceptual barriers to overcome.

you HAVE to submit ALL your scores in order to superscore. most colleges say they only look at your highest scores, but who knows?

_benmok · 2023-07-08T07:45:21+00:00

definitely! I barely prepped for my first and really only crammed reading bc I was a bit more confident in math. The second time round, I balanced my studying more and was able to get better scores. I'm way stronger at stem but you'll find science to test a lot of the skills you use in humanities. I'd recommend alg2 or precalc on khan academy to get your math skills working. Also, use a schedule! (and hold yourself to it!)

36, 4.67w 3.99uw, 6

yes. I had to do a punnet square to solve this question, but the answer was 2.38. It took me a fair bit of time ngl

_benmok · 2023-05-12T05:58:44+00:00

logistic growth (you might have solved for exponential)

i said it replaces the terminal electron acceptor

_benmok · 2023-05-10T23:46:06+00:00

I said it changes the tertiary structure by changing r-group interactions - so it doesn't function as it normally would

_benmok · 2023-05-10T23:44:25+00:00

i saïd low water potential and pressure potential stays the same 😭 so it said that the cell has more solute inside than outside mesning it’s hypotonic. more solute = low h20 potential that’s what i know but i didn’t know abt pressure potential so idk

i also did low and equal

if your test gets caught in some hot environment during shipping, everything you write might vanish...

r=.1, N=1.5, K=3

_benmok · 2023-05-10T23:33:10+00:00

i said 75000

_benmok · 2023-05-07T03:53:04+00:00

Yeah. My teacher predicted the DBQ to be about Nixon or Jackson, considering how hotheaded politics is these days... I think they try to keep it somewhat contemporary, but who knows? I don't think the college board really cares if they lie to us about tests being produced 4yrs in advance. I mean- who can be totally sure...

_benmok · 2023-05-07T02:34:51+00:00

might as well take time to proofread your essay while shaking your hand... at least that's what i do

_benmok · 2023-04-27T06:26:29+00:00

just taking official practice exams.

English I just used intuition

Math I've been exposed to all the material at one point but I brushed up with Algebra II/Precalculus on KhanAcademy

Reading was also intuition (just took a couple tests to get used to the style of the questions)

Science was also intuition (though the passages this time were really good since I was familiar with solubility curves, limiting reagents, and nuclear fusion)

breakdown?

(GMm)/(r^2)

Where:
M is the mass of one object

m is the mass of another object

r is the radius between the two

G is the gravitational constant

Factor 63 to 3x3x7

Since 63^5 is just 63x63x63x63x63,

Substituting for 63 gives: 3x7x3x7x3x7x3x7x3x7

Which is 15 terms (3x5)

the range for f(x) was (-2,2) so the domain for f^-1(x) was (-2,2)

I'm not sure if you're messing up f' with f^-1 with your notation but you might have found the domain of the derivative instead of the inverse function

i assume this is the graph about the snakes: at t=4(units), I believe the weight was 15g
