Molecular Structure And Bonding
This topic gets a little tricky, especially if you are not good at remembering names.
Expect to see at least one question on the geometry of an atom. As the exam does not want you to waste unnecessary time on a simple task, it is likely that the Lewis Dot structure will already be done for you: now it is just a matter of knowing your stuff.

Get Your Study Guide Early
The American Chemical Society sells study guides including the General Chemistry Study Guide.
The first thing you need to do is purchase the ACS official study guide. The book is just over 100 pages long and provides example questions along with explanations for the correct answer. It is separated into the following categories, each containing an impressive set of practice questions similar to the ones you will find on the exam.
- Atomic Structure
- Descriptive Chemistry/Periodicity
- Laboratory Chemistry
In many Gen Chem I courses, dynamics and equilibrium are not discussed, and they will not be reviewed in this article.
The exam focuses on remembering important constants and trends, and that is where a good memory and steady studying can boost your grade on this exam.

How To Tackle Multiple Choice Questions
Ever notice that its easier to find flaws in other people than it is to find flaws within ourselves?I have my theories on the why, but perhaps another day.
Because this also works for MC questions, I find it easier to work backwards.Instead of looking for the right answer, start by identifying and ruling out the incorrect choices.Its so much easier to spot what is wrong than to identify what is right.
First thing is the question itself.Read the question. Look at the answer choices. Choose the right answer.Right? Actually no!
As soon as you start reviewing the answer choices, your mind will be influenced by what you see, rather than what you think.So dont give yourself that distraction!
Instead, read the question and COVER the answer choices.Process the question, and consider an answer or direction.If the question is lengthy or confusing, try to reword the question.Use 5 words or less to consider what they are asking for.
Sometimes the questions are straightforward:What is the major product when 1-butene reacts with aqueous sulfuric acid?
If you studied your alkene reactions, youll recognize this as an electrophilic alkene addition reaction that follows with 2-butanol as the final product.
For questions like this, think of the product first. THEN, look at the answer choices.
Sometimes the direction of the question is not as obvious. Take this ACS favorite: Which of the following is NOT an intermediate in the reaction between?

Fill Out Any Information Before The Exam Starts
Theres another reason to arrive early! When you take the ACS Exam, you arent allowed to start the exam or even break the seal for the booklet until the time starts. However, you are allowed to fill out the scantron with all of your information in both letters and bubbles. This usually takes about 3-5 minutes. Sometimes longer! Students that arrive right on time to the class, will have to spend precious test taking time to fill this out. You will have to fill things out such as your name, student ID, major code, and other information depending on your school and your professor.

What Is The Acs Exam For Organic Chemistry
ACS stands for American Chemical Society. The ACS Examinations Institute creates nationally normed exams for chemistry courses, starting at the high school level and going through the entire undergraduate chemistry curriculum. Whats interesting is that their exams are created by committees of educators who actually teach the course.
Since this discussion is related to organic chemistry, I will focus solely on the ACS Organic Chemistry exam- what it contains and how to prepare for it.
Simply put, the ACS is a standardized test for organic chemistry:
- 70 Multiple Choice Questions
- 110 minutes to complete
- Tests you on 1 or 2 semesters of undergraduate level organic chemistry
Given the time constraints and sheer volume of information, this is a notoriously difficult exam with the national average at just over 36 / 70 questions. Most professors curve generously so that scoring < 60 questions correct can still result in an A.
What is tested on the Orgo ACS Exam?
The ACS is a cumulative exam that will test you on everything you should have learned in the first semester or both semesters .
I say should have because its a standardized test covering a standard curriculum.Most of which your professor should have covered, some of which you may unfortunately have to learn on your own.
This is just another reason to practice with the ACS guide, to ensure you catch every topic on the test regardless of what was actually taught in your ochem class.
But even if youre NOT taking the ACS

How To Prepare For The Acs Organic Chemistry Exam
April 25, 2021 By Leah4sci
If organic chemistry isnt already difficult enough, many schools or professors add to the nightmare by offering the ACS exam in place of your orgo final exam. The ACS exam is a standardized exam administered by professors who dont want to write their own final or who seek a standardized means of testing.
If you ask my students, theyll tell you that its like an Organic Chemistry SAT or ACT, created to torture you just a bit more before escaping what may very well be your most difficult undergraduate science course.
And if youre not taking the ACS?Well, this article still applies, even if your final exam contains only some multiple choice questions .
And regardless of who writes the exam, the ACS or your professor, having a proper strategy for tackling multiple choice questions will make finals week that much less stressful for you.
Lets face it. Multiple choice style questions are different and, dare I say, MORE difficult than open-ended reaction, mechanism, or synthesis type questions.
Before we delve into strategy, I strongly urge you to acquire the ACS Organic Chemistry Official Guide. Sooner rather than later. Buy it for practice throughout the semester, rather than for last minute exam review.

Find The Largest Desk
Sit in the seat with the largest desk in the classroom. There are many sizes and types of desks that chemistry classrooms use. But often there will be that classroom that just has those really small desks. These can be hard to work with when taking the ACS Exam . Sometimes, those classrooms will have a larger desk for people with disabilities, or a few desks or work areas that are just a little bigger than the rest. If nobody will be using that desk, its good to grab this desk just for the ACS exam.
Do you see your desk?
Look at the picture of this classroom. Do you see it? Thats your desk right there. You will have a test booklet, calculator, giant scantron, a scratch piece of paper, and 2 pencils! This is a lot of stuff to juggle while you are trying to focus on taking a timed exam. Reduce the shuffling of these items as much as possible to save time, and focus on working the questions. There are many questions on the exam where you have to reference the periodic table, which is on a different page than the questions. All of the shuffling around can be frustrating and can cause you to lose focus.
