UCAT Decision Making | Syllogisms from Medic Mind. Welcome to our video on UCAT Decision Making. Here, we will go through useful tips on succeeding in Decision Making, one of the hardest sections of the UCAT (UKCAT) ✅
The UCAT is a tough exam, but let us show you our tips for the UCAT and help you succeed. Today you’ll learn how answer Syllogism Questions in Decision Making and feel confident on test day ✅
Here are some of our top UCAT Decision Making Tips:
1. UCAT Decision Making Technique Is Key
On the face of it the UCAT Decision Making question can seem incredibly complex. But by systemically applying technique to each one you can break them down into much more manageable questions.
For example lets start with the syllogism questions. They just seem like a jumble of nonsensical words, but by drawing a Venn diagram you turn a random sentence into clear and easy to follow diagram. And then you can use this to confidently select the correct answer.
Once you have learnt the required techniques and spent time practising them, this section can be turned from one of the hardest one of the most manageable.
This section is not like Quantitative Reasoning that can be managed with strong basic mathematical ability. Which some students can manage without spending time learning theory. If you do not know what you are doing in this section can be incredibly challenging. So good technique can make all the difference.
2. Balance Different UCAT Decision Making Question Types
There are six different question types in this UCAT section. Therefore, it is incredibly important that you have spent time practising each type. Each question type has different techniques and timing tips linked to them. And you need to have spent time on each one to learn these.
3. Make Note Of Your Mistakes
When practising make sure to write a list of all the different question types. Not only will this allow you to make sure you have done at least one of each. But then as you go through make a tally when you get a certain question wrong.
For a section with so many sub-topics, this is useful way to structure your revision, allowing you to focus on your weakest areas. Remember not to neglect the questions you find particularly hard. Everyone has a certain type they struggle but this does not mean you should avoid them! This technique as a good one to apply to all the sections of the UCAT. As they all have different question types with them, so it can help you to keep track.
4. Practise Venn Diagrams
Venn diagrams are one of the most important parts of UCAT Decision Making. As the are key for both the syllogism and the Venn diagram question types. Practising drawing them will get you used to how they work. And how to then apply them to these two different question types.
Then when it comes to the test day, even though it might require more time initially, it will mean that you answer the 5 statements quickly and accurately. But be sure to keep an eye on the clock when practising. You need to have a rough idea of how long it is taking you so as not to run out of time.
5. Ensure To Be Strict With Timing
UCAT Decision Making requires you to move through the questions at a rate of about one question per minute. This may seem generous compared to the other sections, but it is very easy to fall into the trap of getting caught up in a question.

Wow, I can't believe how easy medic mind made this!!! Thanks 😁

[@jeffo8520]

This is fantastic. Thank you

[@msat5231]

you guys are amazing, i appreciate this! wow

[@sathanasivanantham5503]

I have just watched this video and I have my exam next week thank you so much I wish I saw this earlier!

[@donacimento100]

hi Medic Mind, I think your venn diagram for pattern 7 is incorrect as it implies that there are some C that are A and not B. Shouldn't you draw circle C such that it hugs the left hand side of the overlapping area of A and B? There may well be some C that are A but not B but the info doesn't tell us that.

[@Ash-en4ul]

This has saved my lifeeee

[@lydiapremkumar3497]

Thanks for the vid! It was very useful

[@lalayatem3758]

very helpful, thank you. God Bless

[@mike-nwokechiamaka6624]

God bless you Medic Mind🙏

[@dharmx]

Terrific. thank you

[@priscarogi2183]

big thanks!

[@flyingpigeon2812]

For pattern 2 example: "Why are some sights not beaches?" Is that a valid statement to conclude? Since I noticed it wasn't there. 🤔

[@arunchinna7687]

Thanks for the video. I noted In pattern 7, all A can be C

[@dantaylor7999]

Thank you :D

[@saffiyabutt9388]

thank you so much

[@rikhil_8818]

For pattern 11, what is the relationship for C to B

[@zoans6731]

You know for the footwear and shoes, how about some shoes are footwear but not slippers what is the conclusion for that because i couldve drawn my diagram such that none of footwear overlaps shoes on its own but instead it can be aligned with the circle for slippers in shoes. If yu understand😅

[@onyekamichaelugwu47]

Thank you

[@daisylawrence7447]

24:45 is the relationship between A and C not known, ie the A that aren't part of C, we don't know how they are related to C?

[@radhabudhavati8470]

Dear medic mind ,I don't understand the conclusion for SOME A are not B. Why only conclusion is Some A are B .You said we should consider only statements which are 100% sure .But Some A are B also a possibility ...

[@archjanasivasuthan6252]

Hi, thank you for this video. If all A are B, then why are only some A, B please? Or could it be that some A must be B?

[@wr2526]

I have the exact same question, how can we just through logical thinking away, when the entirety of the UCAT is dependent upon 'REASONING', that being rational, I think something isn't right, if All A are B, then it is WRONG to say some A or B, that just doesn't make sense... If someone understands something differently and can back up the statement that 'All A are B' = 'Some A are B', can they please help out here

[@DJRAJEE]

Cheers

[@sawairafarooq4373]

how many total syllogisms questions we will get in real exam?

[@paulcaragay2466]

If all A are B why can you conclude some A are B? Does this not imply that some A are not B?

[@ir4351]

Hey Medic mind i really appreciate this. If the stem said "Many are a", can you say some are not a? Thank you

[@captainclarky5352]

Yes you could say that some are not A if many are A

[@ryosukemurayama9491]

For example, a question states "all cats are mammal. If a mammal is cute, it must be a cat". In this case, how am I suppose to form a Venn diagram?

[@MedicMind]

This fits under a "conditional scenario" - We have a video for this on our UCAT Online Course (www.medicmind.co.uk/ucat-online-course)

[@laurenm7832]

@@MedicMind What if I cannot afford it :(

[@Ferb747]

11:12 What if the question asked ‘Some A are C, but not B’? Based on the Venn diagram you would assume it to be true, but you would have to answer ‘No’ to the question because it’s an assumption?

[@vicmictee2062]

it would be "no" because all A are B and so they can't not be B. i dont think it would be "no" because its an assumption. i think. im not sure i might be completely wrong

[@Ferb747]

So ‘some’ can equal ‘all’?

[@nicolburchell7271]

For pattern 8, if some B are C, yet all A are B, surely it is possible to say that some A are C? As all A are B? How are we to KNOW that there is no relationship there? Would we answer 'cannot tell' or 'this answer does not follow/incorrect'

[@somid7777]

This is prob too late but i think that conclusion is too vague, thats why we say an unknown relationship. Hope it helps

[@elliedodd4258]

Does this still apply to the 2020 UCAT exam?

[@MedicMind]

Hi Ellie, yes it does! We will be launching new tutorials in the coming month, but these existing tutorials are still relevant to the 2020 exam and fully up to date

[@Joonieman]

One thing that isn't clicking is how 'All X are Y' and 'Some X are Y' are both possible. Surely the word 'some' suggests 'some are not' therefore making the latter statement incorrect. Could anyone clear this up for me please?

[@MedicMind]

Hey there! So if the main syllogism (in the title) says 'Some X are Y', then we can take it as 'some X are not Y'. However, if we are deducing conclusions from a syllogism (the mini statements you have to assess to be True or False), it is slightly different.

[@MedicMind]

So for example, If the question title says 'All X are Y', and the sub-question had a statement 'some X are Y' then its TRUE. If the question title says 'Some X are Y', you can deduce that not all X are Y (otherwise this would be the syllogism!), so the sub-question 'some X are not Y' would be correct.

[@abidahad7242]

but doesnt a mini statement saying 'some x are y' when the stem said all x are y, imply that some x are not y?? in which case it would be false? @@MedicMind

[@curismo5526]

Abid Ahad you have to completely go by the statement, if it’s true it’s true forget about what they are implying

[@kyleheslin]

"Some graduates are not mathematicians," is this true because if all graduates are not mathematicians than some have to not be mathematicians because some could be all of them?

[@vicmictee2062]

in pattern 11 when it says that all A are B and no A are C. can you say that some B are C?

[@captainclarky5352]

Yes you can. All cars are vehicles, and no cars are aeroplans. Some vehicles are aeroplanes

[@cathayformosa3561]

Sorry to bothor anyone who sees this; in pattern 7, does it Necessarily means that some A are C but not B? The diagram on the vedio suggests that but I can't work that out. Someone help me plz!

[@rikhil_8818]

No, some A are C and not B is IMPOSSIBLE IMO

[@shayekhabedin4462]

wait... arent there some exceptions to the patterns tho??

[@MedicMind]

There are, we will have a video on this soon!

[@shruthis3516]

Hi, in pattern 6 is it not true that if all A are B, then all B are A?

[@wr2526]

How can 'All A are B' = 'Some A are B'?????, that has to be wrong medicmind can you please clarify!!!! How can we just throw logical thinking away, when the entirety of the UCAT is dependent upon 'REASONING', that being rational, I think something isn't right, if All A are B, then it is WRONG to say some A or B, that just doesn't make sense... If someone understands something differently and can back up the statement that 'All A are B' = 'Some A are B', can they please help out here

[@myucatadmissions]

The UCAT official definitions do not agree with this. They clearly specify that some does not include all (some has to be more than 1 and less than all). So medicmind in this case is unfortunately incorrect.

[@huda613]

“”All beaches are sights” and therefore “some beaches are sights””. I don’t understand. If all beaches are sights, then “some beaches are sights” is false. Because not just SOME but ALL beaches are sights.

[@huda613]

Explain this please?

[@MedicMind]

If the syllogism tells you 'some beaches are sights', then you know thats the final rule, and hence some beaches are not sights. They would have said 'all beaches are sights' if all (not some) beaches were sights. BUT, if the syllogism says 'all beaches are sights' and the statement question says 'some beaches are sights', then this is true because if all beaches are sights, then at least some are. Its a confusing one, but: • If the syllogism says 'some X are Y', then you know thats the FINAL rule. So it can't be that 'all X are Y' otherwise they would have told you (the final rule!). • If the syllogism says 'all X are Y', then the statements 'all X are Y' and 'some X are Y' are both true.

[@huda613]

Medic Mind thanks. I still don’t understand how both can be true but I’ve learnt to just accept it as it is. One way I justify it for myself is that if “all X are Y” and the statement is “some X are Y”, the “some” is referring to the sample, not the entire population of X. For example, if there are 100 X altogether, and All X = Y, If I sampled 50 X from the 100 X, Then “some” (50/100)X = Y.

[@radhabudhavati8470]

Dear medic mind ,I don't understand the conclusion for SOME A are not B. Why only conclusion is Some A are B .You said we should consider only statements which are 100% sure .But Some A are B also a possibility ...
