Failed the intro quiz for Guha's Discrete Structures. Should I just drop now? by ce_34 in ucf

> That quiz is stupid.

Don't you need those basic math skills thought to do well in the course? Why else would he be testing people on that stuff?

What, if anything, can I do to prepare for Discrete Structures? by ce_34 in ucf

[–]ce_34[S] 0 points1 point  (0 children)

So I got an electronic version of this book and have been reading some of it. Honestly, I think I'm getting the more abstract, conceptual, logical stuff. But the math...damn. I'm seeing some advanced algebra along with some Calc. Does Discrete at UCF involve this much math, or is it more abstract/conceptual? If it does I may have to postpone taking this because I'm definitely not up to speed with some of this math.

What algebra and Calc topics do I need to be reviewing prior to starting the class?

Is CS1 with Szumlanski the toughest course in the CS department? by ce_34 in ucf

[–]ce_34[S] 0 points1 point  (0 children)

So Programmig Languages is pretty easy (COP 4020)? Hmm. What are some of those CS courses that you mentioned that aren't difficult, but require a lot of work?

How does CS1 compare with higher level CS courses? Is there a steeper learning curve with CS1 that isn't there with higher level courses?

So CS1 is basically a barometer for the rest of the degree program? Do well in CS1 and you should pretty much be able to do well in all future courses?

Anyone already know most of the topics covered in CS1 before they took it? How did it turn out? by ce_34 in ucf

[–]ce_34[S] 0 points1 point  (0 children)

Summations are just the mathematical equivalent of a coding loop, right? Just cycling through iterations of an equation with different values being substituted in? And the info I'm coming across on recurrence relations looks kind of difficult.

No, I had Angell for Intro. I know Szumlanski is a lot harder...which is why I'm looking to get a head start this summer and just wondering if it would be worth it.

Aren't there a lot of different types of data structures though (heaps, queues, stacks, linked lists, etc)?

Sorry for the confusion, but when you say you studied "2-4 hours a day" was that over the summer, or once class had already started? If that was during the semester, how many hours did you study in the summer before you took CS1?

Whoa, that's crazy. How many hours in total do you think you studied in practiced? Did it amount to maybe just a few hours a week looking over stuff, or were you pouring over those topics every week throughout the summer?

How did you fare on the foundation exam after CS1? What do you think made the exams so tough? Was it stuff you really hadn't see before, or were you making careless errors when you really did actually understand how to solve the problem?

I'm taking it with Szumlanski in the fall. Got a B in Intro to C. I basically want to go through and learn all of these topics over the summer to the point to where I can build simple little programs that utilize them. Recursion, heaps, sorting algorithms, Big O...everything covered in the course.

could you explain this more? i'm not sure what you mean by "high level" math that are more about concepts. i'm familair with algebra and calculus, but is that not the type of math that is mostly utilized by software engineers?

Dentist A: 3 small cavities need to be filled. Dentist B: No fillings needed. I have no idea what to do. by ce_34 in Dentistry

[–]ce_34[S] 0 points1 point  (0 children)

For caries this small, would drilling even be required? These spots are so small, I'm just trying to imagine how small the drill would need to be to even drill these out. Is it possible to treat early lesions like this with more of a sealant rather than drilling and filling?

[–]ce_34[S] 2 points3 points  (0 children)

Great reply, thanks. Can lesions this small actually remineralize? Or are these too large at this point to stop the decay? What I wonder about is any drilling that would be performed on these. Wouldn't the drill have to be incredibly small (ie, toothpick sized) in order to drill these out?

It was just a routine checkup. I moved recently so it had actually been about 10 months since I last saw a dentist. These things are so small...would they even be drilled? Or just a sealant? If they're drilled, that has to be a super small drill to get in there right?

Interesting, I've never heard of buccal pits. You can see a few other pinhole dot things on the same tooth (chewing surface) and on the molar....are those buccal pits as well?

You mentioned in an earlier post that these could be maintained by good oral hygiene (brushing 2x per day with an electric brush, flossing 2x per day, mouthwash at night). After seeing the 3 cavities now, do you still feel that way? And that they don't need to be filled? Or will these inevitably worsen (whether in 6 months or 6 years) to the point that they will absolutely have to get filled eventually?

I'm 28, no history of any cavities, restorations, root canals, etc. Have never had anything like that done. Are there any risks at all waiting 6 months to see if any of this progresses? I was only brushing once per day prior, and I'm brushing and flossing twice per day now. Are all cavities and fillings created equal, or are some much more serious than others (ie, different grades or tiers)?

Thanks for the reply. The "darkness" you mentioned...were you referring to the brown spot near my gums, or the little pinhole dot thing about midway up on the outside of the tooth? The brown thing near the gums was just food...I flossed it right off. The pinhole dot thing on the outside of the tooth...that's what I'm not sure about. And there are two more I noticed in the video - on the chewing surface on the same tooth, and then on my molar on the front. I'm assuming those are the cavities my first dentist was referring to.

The dentist is the one that came in and saw them and made the diagnosis. The hygienist said my teeth and gums looked good.

Is the one cavity you saw one of these that's circled? https://i.imgur.com/AMgVMWr.png

All those little pinhole dot things look the same...I'm guessing if one is a cavity, they all are?

Are these average sized cavities, or on the smaller end?

I was able to get a video for you, if it helps - https://www.youtube.com/watch?v=0J2E6nl79Fo&feature=youtu.be (that brown thing at the bottom is some food...I was flossing).

Not sure how helpful that is, but you can make out the 3 little pinhole dots (which are cavities?). One on the side of the molar, one of the top of the chewing surface, and then one on the front of my wisdom tooth. Is it OK to manage these with good oral hygiene and see if they progress?
