    Gotta read more closely. TOTAL MASS. I read it as "astronomers estimates of galaxies' mass" or something. I was like "even if its a tiny percentage, the mass should change if there are more of them". Didn't realize it was in terms of total mass of the universe. I'm also drinking rn though so maybe that was not a good idea lol

    Is it bad to read an answer, think it's right, and pick it without reading the other options? Specifically for RRE.

    I went 21 sec over time but I felt confident about A when I read it, so I could have saved time by skipping B-E. Would this be potentially detrimental?

    @Rose955 Hey I do this for most questions. I'm doing pretty well so far. I go over on certain types of questions because I struggle with those, but I am consistently under on time for many other types of questions bc once I find the answer, I know its the ONE right answer.

    You need to be able to be confident that for some types of questions you are good at understanding and solving them with less effort than other people, thus saving time. Because there are likely other questions in which you are less capable of solving than other people and will need to spend MORE time to solve them.

    I like to think of it as using the skills I do have to build up a bank of time that I can then spend on questions I need help with. Time = Help & You can "buy" time if you save up on the questions you are good at.

    @LindaLopez Only one in the entire course? For the whole curriculum so far?

    Its been over a month since you commented this. Have you started to get more of them right since then?

    I've been answering these questions in anywhere from 6-20 minutes, and getting them correct. I see in the comments people saying they are only a few seconds over yadayada and I think that's great, but I just wanted to remind you that if you're not able to get the answer for 20 that's literally fine. The important thing is that you're understanding the question and implementing what you've been learning carefully, and most importantly correctly, in order to get the question correct!

    @BreanaNunez Precisely. Accuracy before speed. If you're fast, but inaccurate, all that guarantees on test day is that you'll be out before the rest, not that your score will be higher

    The overwhelming majority of the mass in the universe is composed of something else, no galaxies.

    These spelling mistakes are becoming too common not to be confusing.

    i need to read the question stem more carefully. I focused instead on how they found more galaxies and chose c...

    I am getting them right, but I am not sure how to get my time down. I am always 12-15 seconds over.

    Watching the explanation made me realize I made an assumption about A. In my perspective, "a tiny percentage" in relation to the universe mass could still be a huge number. It kind of feels I thought of it as "many = large amount".

    I was overthinking my reasonings trying to do POE. Anyone have any tips to stop doing that esp with POE?

    @QarimatOgunneye See, I picked A specifically because "a tiny percentage" isn't defined. It could be 1%, it could be 0.000000000001%, we don't know. Therefore, it's more likely to be true that astronomers' estimate of the mass of the universe is virtually unchanged because the mass of each galaxy adds virtually nothing to the total. (in reality, the mass of the universe hasn't changed at all, we've just changed how we observe it, ie with more galaxies)

    To answer your question, I would say you shouldn't make assumptions about what vague words mean and just take them at face value (YMMV tho)

    Getting all of these right, but my timing is dog water.

    I got this one in 45 secs!

    Tangentially, I think E actually deepens the paradox. If they can't even agree on the proper procedure for making an estimate, and all use different techniques, but most still agree this has no impact on their resulting estimate, then that is just further proof that something more complex is going on.

    i had A smh i changed it to be B :/

    Ok I am starting to get them right.

    Pretty much you have to make a "logical assumption" based on the info in the stimulus... all these scientists think mass remains the same because we barely know the univerise anyway so no matter if we discover another 40 billion galaxies its prob like 0.01% of all galaxies lol < I guess this is what helped me.

    Yeah, I am not good at these RRE questions. Maybe I'm too stuck in support spectrum mentality. That makes it difficult to go through POE because I think I'm ruling answers out for the wrong reasons. It means I'm going through the list of answers looking at each one as a possible explanation rather than accepting as true and determining how they help explain the stimulus...🫤

    i feel it's easy when all i do is really assume in real life lolz

    I forgot that I was supposed to assume that each answer choice was correct :/

    Am I the only one finding these to be the easiest questions so far? I feel like main conclusion and MSS questions may be harder for me. Lol.

    I wish. I think these are the hardest for me. The others felt easier to hunt for the answer. With these, it feels like there can be a million reasons why haha

    @cj3village agreed, MBT is by the far hardest. These ones aren't the easiest, but with practice become pretty doable. I would say main conclusion questions are the easiest for me!

    Good news: getting these questions right... but I'm doing it with 3 or 4 mins each time. I know I shouldn't worry about time right now but I can't help but think at some point hopefully it goes down.

    I decided to switch my answer from A because I felt "tiny" was ambiguous. A tiny percentage could be 1%, so wouldn't accounting for 40 billion more galaxies potentially up that tiny percentage to like 3%, in which case the mass of the universe would be changed... Or am I overthinking. #feedback

    Virtually unchanged is not synonymous with unchanged.

    For example, a "tiny" percentage could also be 0.0001% (not unheard of in the realm of science), meaning that even if the percentage went up to 0.0005%, that could be considered an insignificant increase by astronomers, as 99.9995% of the universe's mass is not made of galaxies, as opposed to the previous 99.9999%.

    Just sharing my experience in case anyone else is feeling a lil fatigued- I stopped on this question yesterday feeling frustrated because I was NOT understanding it at all. Back at it this morning, and it totally makes sense now. Studying consistently is key, but sometimes you really do just need a break and a good night's sleep!
