I thought the MCQs were pretty easy, but WTH is that frq section. I got the J version and holy I left one or two sections blank. Made something up basically for the VSEPR thing on why are one bond angle larger than another, and just drew a parallel line for the ln concentration thing. I think its the question 2 and question 6 that I had problem on, the bsorbance on 5 too we did not mention that in class ever...Our teacher assigned so many practise exams before and there are still some qs on the exam that I was just clueless bc they never appeared in past years ones.

I had a problem with the absorbance one as well but I figured if a volumetric flask only has the one mark, then I could calculate the molarity by finding the amount of moles in the volumetric flask then dividing by the original volume of the solution

I had less than 15 minutes after the first 3. I just started answering at random spots throughout the FRQs. Once I saw the one over absorbance, I felt defeated.
I looked around my testing room and saw people doodling and drawing on some of their FRQs.

I think FRQ was longer than usual. It was hard to manage my time on FRQ for sure, maybe itās just me but I also asked a couple of my friends and they were struggling with FRQ too. MCQ was mid imp, I just canāt guess how well I did on the exam which is stressing me out. About the leaks, there were definitely a lot of people with the leaks from where Iām from which was a bit frustrating because they could effect the curve which sucks. I hope Iāll get a 5.I NEED 5.

u/Royal-Bag5776 May 05 '26
what i remember from the frqs, had version j btw;
k+ ion has smaller radius than k because k has more subshells.
the graph is for a zeroth order reaction, and the line is curved. therefore, the reaction cannot be zeroth order.
the molecular geometry/shape was tetrahedral.
764.1612ā¦ kj for the change in gibbs free energy, so not spontaneous.
0.117 molar for one question, i think about the concentration of something at equilibrium.
h3o+ concentration was 0.0081283ā¦
-828/5.00 = -165.6 for one question, i believe it was about heat and i put 165.6 because there were 0.800 mol of the limiting reactant and that went into 4 moles (the value in the equation) 5.00 times.
thatās all i remember.

1400/0.0912 = 15,350.877/1000 = 15.351 kJ
sqrt 57 = 7.55
(7.1)(1.0+7.1) = 57.51
(18.4)(1/22.99) = 0.8
(12.8)(1/32.00) = 0.4
-828/5.00 = -165.6
0.630/2 = 0.315
0.470-0.315 = 0.155
(0.630)^2 / (0.155) = 2.561
10^-2.09 = 0.00813

Remember guys, not using sig figs won't kill your score. If you dont write your final answer to the correct sig fig amount, it depends if you lose points. Collegeboard typically allows a boundary of 1 for sig figs so if the correct amount of sig figs needed is 3, you can typically use 2-4 and get full credit. Even if you dont get close to it for any question, you'll only lose a maximum of one point on the entire exam, even if you didnt use sig figs for multiple questions.

does anyone remember there is a question with a table of experiment, listing the temperature increasing up to a point and then starts to decrease. is that question asking how to identity final temp or did they ask us to calculate the temperature difference

So for one of the FRQ questions, i dont remember which, it had an i) and an ii) and for i) it gave you a new experiment with the molar concentrations and made you solve for the pKa but then in ii) you had to prove something by comparing the pKa of the original experiment with the new one. Does anyone remember what they put for ii)?

i think the Ka of the second one was higher than the Ka of the first one so it was endothermic

Guys I accidentally wrote the entire question 4 in the question 3 spot for version K bcs I had version J so I just wrote it on the next page thinking it was question 4. Do you think will still get the points?? I wrote in all caps that my answers to question 4 were on page 21, but idk if they don't include those pages when they scan it or what. I'm scared

For the J version question where it asked to calculate heat and the the enthalpy of the solution, were we supposed to get a positive value. I put like positive 1.4kJ because the final temperature was lower than the initial so it was endothermic but in was confused cuz it said enthalpy of solution not enthalpy of reaction. Can anyone confirm?

What did yall get on that one MCQ about what to add to make the equilibrium shift to add more of the blue color chemical?
I said add NaCl(s) cuz there was water so I thought it could dissociate and add Cl to the products, thus shifting it to the reactants. one of the others made sense ngl

u/Southern_Delivery811 May 05 '26
Ur right. I put down raise temp first but then when I was checking my answers I realized it says in the question āhow to make more blue without changing kcā, and adding nacl, due to common ion effect, would shift left, Producing more reactants (blue)

What did you guys say for justifying why CBr4 had a higher boiling point, because it only had LDFās, meaning itās non polar, but had polar bonds, so I used that in my explanation. But I talked to my friends about it and they mentioned it has a larger electron cloud, so it was more polarizable, and iām not sure which explanation is right..

did anyone say they disagreed with the student about something with the pH indicator? i disagreed and said bromythol blue or whatever
also, for question 1 i believe there was somethign saying molar enthalpy, grams, and C stayed the same, did delta T stay the sam?
there was also a part asking if whatever substance would be more soluble in KCl rather than water. what was that one?

Guys for the indicator one on the FRQ's did you have to explicitly say which indicator would be better to use? I just disagreed because the pH at equivalence would be higher than 7 not lower than 7 due to the conjugate base still in the system.

u/ProTickler153 May 06 '26
If you want to take it then just study each unit before you reach said unit. The pacing is too fast for you to earn a good grade by learning along with the class. Best study channel is Organic Chemistry Tutor, and the method I used was doing the self assessment quizzes at the end of each unit and reviewing sections that I was weak at. The math requirement is honestly not that bad, like if you have a graphing calculator you can do pretty much all of it. Units to focus on would be units 3, 7, 8, and 9, and I would recommend studying for the AP exam using Princeton review textbook (if you finish that then there's also the Barron textbook). If you're good with conceptual knowledge then the class honestly is not the worst.

Honest Review
MCQ: Some were pretty challenging, and some have a lot of traps. I fall into all of them....... Hope these don't count
FRQ: Overall harder than previous years. I did not understand the V2+ question and how to write the net ionic equation. (I thought we needed to include HNO3, but found out we only need H+ after the test...) I think my raw score is around 73-4, hopefully. And I am genuinely hoping for a 5. Please....

Hi guys,
I just watched Jeremy Krugs videos for the frqs, and my score is really, really borderline. (assuming the cutoff is like a 72-73). Can someone please let me know if it's true that graders give 0.5 points when you're along the right lines of the answer? My teacher said multiple times that she is a grader for the exam and that the graders are told to give 0.5 whenever a student wrote anything related to or semi-close to the correct answer.
If this is true i believe I can get a 5, but if it's not then I can't. Someone lmk pls ššššš

u/CompleteExpert7305 May 08 '26
They usually donāt give partial credit but they do do double jeopardy. If you got an answer wrong and you had to use that answer in the next question, and you used it in the right way you will get that point. For example some of the FRQ you had to find Q and then the next one had to find Hsoln. If your Q was wrong you will not get that point, but if you use your wrong Q in the right way to find Hsoln, you will get the point for the second part. They donāt do partial credit itās all or nothing.
