Yes it's cumulative! Dr. Lavelle said that it would correspond to how much time we spent on certain outlines (topics), so going over the syllabus would be your best bet.

Angela Marie Guevarra Dis3F

Thank you so much this is extremely helpful!

I also use the Pomodoro method, but sometimes I change it so I work in 30-40 minute intervals since the 5min break is too short for me. For background noise, I recommend using Noisli if music is too distracting for you. Recently I've been listening to calm video game/Nintendo music like the Animal C...

Thank you everyone for all the resources!!

Angela Marie Guevarra Dis3F

Honestly, just knowing that I'm trying is what's keeping me grounded. Personally, this class (or any of my classes) haven't been easy online and it's okay if I'm not doing as well as I thought I would going into the course. Don't stress too much, you're doing your best :)

Angela Marie Guevarra Dis3F

I'm planning to spend time more time with my family (and friends, virtually), maybe binge a few shows, and focus on hobbies I wasn't able to during the quarter :)

Angela Marie Guevarra Dis3F

Considering everything, I think I'm doing alright. Feeling less overwhelmed than I was recently once I put all my worries into perspective. This quarter hasn't been the best but I think I've learned a lot that will help me tackle future quarters.

Angela Marie Guevarra Dis3F

I would assume no, since I haven't heard Dr. Lavelle mention any extra credit throughout the quarter. I would still suggest doing it if you can since it's helpful for future classes.

Angela Marie Guevarra Dis3F

I plan to go over my notes then go to review sessions and do a lot of practice with the textbook. Practicing problems on my own has been challenging but I think it's the best way to prepare.

Angela Marie Guevarra Dis3F

Will any of the review sessions throughout the week be recorded? Or will they all be live-format only?

Angela Marie Guevarra Dis3F

I didn't do well the last midterm and I was pretty disappointed with myself. At the end of the day though, you just have to forgive yourself for those types of things and learn from it. Being a first-year with her first run-through of the quarter system, and struggling with the online-learning forma...

Angela Marie Guevarra Dis3F

It's been going okay for me. I've had quite a number of bumps throughout the quarter, since the last time I took chemistry was years ago and overall transitioning into being a student again has been challenging (especially with the quarter system). But overall, I've learned a lot about myself and wh...

Angela Marie Guevarra Dis3F

I plan to make study guides for myself and do a lot of practice problems from the textbook. Hopefully I'll go to more UA sessions since they were helpful for me in the beginning of the quarter. Good luck to everyone :)

Angela Marie Guevarra Dis3F

Honestly I'm still working on this, as I've realized my study methods in high school weren't the best for long-term understanding, but recently I've been trying to do more of the textbook problems since I have more difficulty with application problems rather than conceptual ones. It's been hard but ...

Angela Marie Guevarra Dis3F

Reading everyone's responses has been really helpful! Ideally, I get a good amount of sleep the night before and eat a good breakfast to take care of my body before tests. Unless I have something else going on before the test, I'll distract myself with music or videos to get me in a good mood, or I'...

Angela Marie Guevarra Dis3F

If I don't have too much going on for school, I try to let myself have my own day to unwind since I've usually been studying a lot the days prior. I'll call a friend or two, watch a show/movie, journal, and catch up on sleep. :)

Haha how fun! Usually I like to learn/make choreos or take walks outside to get some fresh air :)

Usually this happens to me if I've been logged into CCLE for too long. When this happens, I just reload the page then log into CCLE again. I don't think you need a VPN to view the lectures, at least not in my experience.

Angela Marie Guevarra Dis3F

Based on how the class has been going, I wouldn't expect to have or depend on any credit opportunities.

Angela Marie Guevarra Dis3F

I wasn't feeling the best since I felt like I did better on the first midterm, but I'm glad that Dr. Lavelle's grading isn't too harsh on students who are having some trouble. Wishing us all the best for the final, we got this!!

Angela Marie Guevarra Dis3F

This site has a really helpful graphic when it comes to memorizing the trends https://sciencenotes.org/periodic-table-trends/ Thank you so much for this resource! Is everything listed here all that we should know for the upcoming midterm? Also, did Dr. Lavelle go in detail about metallic and nonmet...

Angela Marie Guevarra Dis3F

Can we use the terms Lewis Acids and Lewis Bases interchangeably with cations and anions, or is there an important distinction between using the two sets of terms?

Angela Marie Guevarra Dis3F

Expanded octets can have more than 4 bonds! You can look at phosphorous pentachloride as an example (it has 5 bonds). However, even expanded octets don't typically go beyond 5 bonds (Z=10), so don't draw an unlimited number of bonds just because the atom has d-orbitals! Good to know! Can anyone exp...

Angela Marie Guevarra Dis3F

Are we able to annotate on the sheets? I'm pretty sure it's a no but I want to make sure. Unfortunately the sheets have to be completely blank for exams, so we can't annotate on them for the upcoming midterm. But that shouldn't discourage you from annotating in general if that helps you study (I've...

Angela Marie Guevarra Dis3F

Thank you so much for posting this! I've been having trouble understanding them but this helps condense what I should know :)

Angela Marie Guevarra Dis3F

Hello, I'm in the same boat! Considering the class size, I'm sure there are many other students who are in the same situation. While I think I did okay of the first midterm, my score was still lower than what I was aiming for. Let's study well and do better on the next midterm and final :)

Angela Marie Guevarra Dis3F

Based on what I heard from upper grads I know, I'd say that taking them during separate quarters would probably do you more service than taking them simultaneously. Again though, it's up to you! Whatever you think you can handle is the best option for you

Angela Marie Guevarra Dis3F

There's been a number of times throughout lectures that Dr. Lavelle comments that the material is familiar to us from high school, however, I didn't learn the specific information during my time in high school. I was only able to take normal chemistry since my school didn't offer the AP class. I rea...

It's relieving to see that so many people are finding ways to work around studying at home. I study and concentrate best in libraries and cafes, I find that the public aspect of it keeps me more accountable and stops me from indulging in distractions. Trying to achieve the same thing at home is chal...

Angela Marie Guevarra Dis3F

Hello, Dr. Lavelle mentioned that we'd learn about naming compounds later on, but we don't need to worry about that for this upcoming midterm. All such necessary information would be given. I'd just advise you to remember the formula for butane (C 4 H 10 ) and know what the products of a combustion...

Angela Marie Guevarra Dis3F

Unfortunately, Dr. Lavelle said during his office hours that there will not be any more Audio-Visual Focus Modules. I was pretty bummed when I found out, but I understand that he wants to focus on other ways to support us as students. Plus he's provided us with a lot of resources like his office hou...

Angela Marie Guevarra Dis3F

I'm pretty sure the grades will be posted after everyone has taken the midterm, and since certain questions have different point values, I'd assume sometime this upcoming week. I can't say for sure though. Don't stress too much everyone!

Angela Marie Guevarra Dis3F

950000 only has 2 sig figs since we only consider 9 and 5 as significant, seeing that we can rewrite it as simply 9.5 x 10^5. But with 80060, those zeros between the 8 and the 6 are important. We cannot simply write 80060 with only 8 and 6 without those two zeros, thus it has a total of 4 sig figs. ...

Angela Marie Guevarra Dis3F

Hello everyone! I was at his office hours when a student asked about it, and he indeed confirmed that he would not be posting any more modules for the following units. It's a bit of a bummer since they are so helpful, but I'm really thankful for all that Dr. Lavelle has done to provide us resources ...

Angela Marie Guevarra Dis3F

Happy Halloween everyone! Since I couldn't go out this year, I had a self-care day this Halloween which was really nice after our midterm :)

I usually watch shows, talk to friends, play a game, or take a walk outside as a form of relaxing. Anything that I can immerse myself into that isn't school or work related helps me destress and get my energy back up.

Angela Marie Guevarra Dis3F

Dr. Lavelle has confirmed that we will not need to submit any form of scratch work since the midterm is completely multiple choice. You will need to show your TA your constants/equations and periodic table sheets before starting the test though so they know that they're blank.

Angela Marie Guevarra Dis3F

I think practice problems will be your best friend, including Sapling, textbook problems, audio-visual module assessments, and UA sessions. Doing this will solidify your understanding of the content conceptually and how to apply it logically. :)

Angela Marie Guevarra Dis3F

Thank you so much for making this! This is super helpful and I love the way you organized it.

Angela Marie Guevarra Dis3F

I am a current student in Chem14a and I suggest doing as much practice as possible as a form of studying. The audio-visual modules have helped me a lot to reinforce and test my understanding of the content. UA sessions are also a good resource since the UAs are previous students who have been in you...

Angela Marie Guevarra Dis3F

Based on how I perceive each resource, I think the audio-visual module questions and the textbook problems will be most similar to the exams. I assume this for the module questions since Dr. Lavelle creates the assessments, and as for the textbook problems, he said he would use some of them in the t...

Angela Marie Guevarra Dis3F

Like Lavelle mentioned, I highly recommend UA sessions since the UA's give additional practice problems and work them through with you. They can give you advice on what they did to study and succeed in the class, and different methods that might be easier to utilize for problem-solving. Additionally...

Angela Marie Guevarra Dis3F

Hello there! I'm also a freshman so I am still in the process of adjusting to the college lifestyle like you. So far, I've found that planning ahead and giving myself time to take breaks helps a lot. Once the syllabus for each class is given out, I like to make a rough schedule of what I should comp...

Angela Marie Guevarra Dis3F

Overall, I think practice will be your best friend for studying in preparation for midterms. Complete the audio-visual modules and redo the post-module assessments until you get all of them right. The same goes with the homework - do each problem thoroughly. Dr. Lavelle said he would use some of the...

The Sapling website is correct in saying that it should be raised to the positive 2. Keep in mind that 291.7 is 10^2 times greater than 2.917. The value that is is 2.917 times 10^-2 is instead 0.02917. When the exponent is a positive value, you move the decimal to the right to produce a very large n...

Angela Marie Guevarra Dis3F

Dr. Lavelle explained in the Audio-Visual Focus-Topic Video that you want your stoichiometric coefficients to be whole integers. Thus, if you run into a situation where the reaction is balanced but contains a fractional coefficient, simply multiply all coefficients by whatever value is in the denomi...

Hello there! I took chemistry my sophomore year of high school, so it's definitely been a while. There's a lot I need to either re-learn or learn from scratch since we didn't cover it in my high school class. For going over basics, I recommend CrashCourse Chemistry on youtube! Hank Green covers topi...

Angela Marie Guevarra Dis3F

Hello there, I'd love to be part of this study group! In terms of meeting virtually, perhaps meeting 2(?) times each week would be helpful for those with time conflicts on specific days. This way, we can accommodate for everyone. My ig is @_angelamarieg if you'd like to get in contact! :)
