How did you guys find it? :)

It was literally the easiest exam out of all of them (methods and spec) ;D

no cap

Maybe slightly better than Spec 1 exam..at least time wise
-
much easier than methods :P

What do you guys think about the raw 40+ 45+ and 48+ cutoff scores respectively for this year? :D

Definitely much higher than last years for sure
-
Yo, I think I dropped 2 on exam 1 and 4 on exam 2, what do yall think I can get?
-
Perhaps a 47?
-
Can someone estimate my study score?
SACs:
70% (SACs were cooked tho in a strong cohort)
Exam 1:
32-34ish/40
Exam 2:
70ish/80
I don’t wanna look at solutions so I’m assuming I lose a few more marks then I know I lost
-
Thoughts on my study score?
GA1: High A+
GA2: 29/40
GA3: 69/80
-
Much better than Exam 1 and Methods but this will definitely have a high average, think I can still clutch a 35 raw tho.
-
would a 50-60% get a raw 30? or lower :'( ?? Honestly thought I did good in the exam but then I saw the solutions...... ye nooooooooo
-
What would
Rank 2 out of 9 (Alright - ish to weak cohort)
EXAM 1: Think 30/40 (Being generous with consequential marking here)
EXAM 2: Around (70-75)/80 Assuming I lost marks for silly mistakes. Haven't checked solutions yet.
I was aiming for about a 35 raw in spesh

I feel like I must be missing something really simple if I'm wrong, but for multiple choice Question 19, isn't the answer B = 0.06?
\(\begin{aligned}\textrm{Change in momentum }
&= m\left(\vec{v}_f - \vec{v}_i\right) \\
&= 0.02\left(2\vec{i}-7\vec{j} - \left(2\vec{i}-10\vec{j} \right)\right) \\
&= 0.02\left(3\vec{j}\right) \\
\end{aligned} \)
So the magnitude is \(0.02\times 3 = 0.06\).
What, if anything, is wrong with this?
Also, I'm curious to see how Extended Response, Question 4d will be marked, since clearly CAS only gives approximate solutions, whether some additional evidence needed to be given that those are the ONLY solutions for t in [0, 40] (eg. drawing graphs of \(x_a(t)-x_d(t)\) and \(y_a(t)-y_d(t)\) and locating zeroes), and so there is no point of collision.

This company got b for that multiple-choice question!! A lot of the answers would varied from the different company suggested solutions. I think I'd get around 60/80 for Exam 2 and hoping that's still 35/50-ish according to TSFX study score predictor ahh
-
I got B too for that one(as well as B for question 9).

Yes for question 9 the answer is B, since the tick mark at (0, 1) should have gradient –1.
-
I think I got around 70-75% in exam 1
And 75-80% in exam 2.
Can someone predict my ss, could I get 32-33 or is that unachievable at this point?

That definitely seems achievable. Seems like you could get even higher than that most likely
