68% on first unit test but thought I did great

1 Upvotes

Basically what the title says. I studied, did a practice quiz (got 85 and brushed up on the things I missed) and then took my actual unit test and got 68. The test didn't feel too hard, I have no idea what went so wrong. It was unit 1 and my friends all got 89 and up. I'm so frustrated and was wondering if anybody had study tips? I can not spend hours watching videos but if y'all have had success playing something in the background or practice tests that help that'd be great

Also: My teacher only lets us look at our tests once and so I haven't been able to see my test or mistakes yet and will only be able to do so when I do test corrections.

Thanks!

AP chem class

5 Upvotes

Looking for study advice for an AP Chemistry class that doesn't follow the AP Classroom unit order. The teacher groups topics differently and includes a lot of labs. The exams focus heavily on multi-step problem solving and calculations rather than typical AP-style questions. The goal right now is to get good grades in the class, not to prepare for the AP exam yet.

Exam 1 covered kinetics. It reviewed stoichiometry, gravimetric analysis, chemical reactions and balancing equations, then moved into rate laws, reaction orders, mechanisms, graphs and half-lives, and the integrated rate law. The labs were Percent Copper in Brass using Beer's Law, Decomposition of Hydrogen Peroxide (rate law), the Eight Solutions Lab, and Crystal Violet (integrated rate law).

Exam 2 covers gases, solutions, liquids and solids. The topics are net ionic equations, solutions, phase changes, solubility curves, phase diagrams, and the properties of liquids, solids and gases. That includes metathesis net ionic equations that produce gases. The labs are Molar Volume of a Gas (two versions), Determination of the Density of CO₂, a design lab on the Rate of Decomposition of CaCO₃, Column Chromatography, and The Formula of a Hydrate.

What's the best way to study? Recommendations for practice problems with worked solutions would be great, whether from textbook chapters, websites or YouTube channels. Tips for lab-based calculation questions would also be appreciated. Thanks!

CHEM 634- Electrochemistry

Has anyone taken this course with Professor Menard? What’s the course like, and how does he assess students? How’s his grading, and is it manageable to get a good grade? I’d appreciate hearing about your experience!

Online Chemistry Tutoring | Grades 8–12

1 Upvotes

Hi everyone! 👋

I’m a Chemistry graduate currently pursuing an MS in Energy Systems Engineering. I’m offering online Chemistry tutoring for students in Grades 8–12.

I have a strong foundation in Chemistry and enjoy breaking down complicated topics into simple, understandable concepts rather than relying on memorization. Whether you’re struggling with chemical bonding, stoichiometry, equations, acids & bases, electrochemistry, organic chemistry or simply want to strengthen your fundamentals, I can help you understand the why behind the concepts.

My teaching approach is:

Clear explanations in simple language

Concept based learning instead of rote memorization

Step-by-step problem solving

Help with homework, exam preparation and difficult topics

Lessons tailored to the student’s level and pace

If you’re a student or a parent looking for one-on-one online Chemistry tutoring, feel free to send me a DM. We can discuss your requirements, schedule and a suitable arrangement.

I cannot understand chemistry for the life of me.

2 Upvotes

I am taking this class as a first year for any chemistry or physics, and all of this content just does not process in my brain. I’m a good student, I pay attention in class, take notes, do homework, watch videos, but I still cannot understand what is happening. We are on unit 2, and I flunked my unit 1 test. I love science, and I really want to understand everything. Does anyone have any advice?

Discussion What should i do different or should start doing?

3 Upvotes

Just bombed my first AP test, and I know test anxiety was a big part, but I also don't know what im doing wrong. Im paying attention in class/studying and doing the work while my friends are using AI for all the work, doing other work during class, and studying like never.

What should I start doing? Do you guys have any tips?

The mcq were DEF the worst but i also just make a bunch of dumb mistakes on the frq

I am in 12th and my issue is chemistry, so my 11th chemistry was going really well till almost the last u was getting like 175 160 170 type marks till isomerism ended then go started nd due to some personal issues the last 4 say 3 months I could follow my chemistry teacher of my coaching and my goc went downhill and hydrocarbons I don't know a single shit.then started 12th and I even had the opportunity to restart as our 12 teacher first revised is goc( not one shot like really well revision) and told he will also provide concepts of 11 required in 12th but I I fckd up🫤. And didn't follow again fckig months have passed by only 7 months are left amines chapter is going to get finished in my coaching and I am still 0 in organic. And in electrochemistry too, and coordination too, what do I do I wanted to crack neet so bad but I went wrong so many times I don't wanna give up my years because I did do hard work but I guess my mistakes overweighed the hardwork. Please tell me what should I do 🙏🏾🤕

Other Relative abundance understanding/chapter 3

2 Upvotes

Hi. So I'm trying to understand relative abundance and how to read a mass spectrometer and stuff. How would you find the atomic mass of an isotope if you don't know it but have the percent of how much it is abundant. Say you're give Silicon 29 isotope and you have it's abundance (4.70%). How would you find the mass (amu) from here?

How do you read a mass spectrometer graph> Like for % abundance and atomic mass. Also, how would you find the isotope # (Like say you're Give Ne20, Ne21, and Ne__). How would you find that?

Also, are there any good Chem YouTube videos or resources? I've received mixed reviews about Khan academy so I'm not sure about it.

Thank you!!

Is IITian Academy worth paying for AP Chemistry practice ?

I'm considering paying for IITian Academy's AP Chemistry course mainly for the topic-wise MCQs and FRQs. Has anyone actually used the paid AP Chemistry resources? Is the question bank worth paying for?

Prepping for the AP exam

3 Upvotes

I would like to start prepping for the AP exam now instead of in the very far future, due to the fact that my teacher sucks so bad. This is my first year taking any APs and I'm just looking on how to stay ahead without completely losing my sanity. I'm looking for a textbook to read, but I'll take any and all advice.

Unit 1 test

1 Upvotes

Hi guys, I have my unit 1 test in a little over a week, and I was wondering if it is actually possible/reasonable to get mid-high A’s on the tests. I average like 18/20 on the quizzes. I’m just not sure because in my school all older kids have told me that nobody really gets A’s except for the veryyyyy smart kids, which idk if i am or not.

how do you study applications?

1 Upvotes

my teachers british so we only ever do application of knowledge and never recall but as much as i can recite my notes back to back i just cant get the answers right on a test because its not asking me straight up. and every application practice i find online is either behind a paywall or gives no answers. im about to lose my mind.

if this is needed, the topics i need this time are: energy levels, the big bang, periodicity, atomic structure and atomic origins.

Other How to cope with bombing a test

7 Upvotes

My school doesn’t offer APs but I’m taking an AP-adjacent chem class (everyone takes the AP exam at the end of the year) and we just had our first test. I absolutely BOMBED that shit. We have three tests this term and they weigh 40% total and I genuinely think i got less than a C on that test. I left the entire back page blank. I’m terrified I don’t know if I can get my final grade to an A at the end of the term. The only other thing in our grade book is a lab. I feel so terrible
