# Trinity college admissions test engineering

#1
Hi all, I have been invited to a trinity engineering interview. I have looked at the pre interview paper. I have watched the engineering mock interview on youtube, where the professor said a good students answers 5 of these questions. By this, does he mean getting the correct answer in the five of them, or going on the right track, since the questions are extremely difficult. Thank you

I'm doing the test aswell. Maybe he meant 5 mostly correct solutions. Looking at the practice test, 5 seems like a reasonable amount.

Yes that seams plausible, getting 4 questions correct or 5 seams reasonable, also, would you happen to know if the statistic questions can be done by reasoning( as in explaining the probabilities and getting to the answer) without actually using statistical notation?

I imagine you'll get a more concise and pleasing solution using e.g. binomial coefficients but anyway you'll have to reason how you do each step.

you can explain your reasoning in words; I'm sure that adding some maths would give a better answer.

(I would see it as a combinatorics question I e. how many rearrangements, as opposed to a probability question)

I worked backwards from the answer as I haven't learnt combinatorics. If it wasn't a 'show that' question, I probably wouldn't have been able to answer it.

That’s exactly what I did too, seeing that that counts as a right answer, getting 5 correct is far more reasonable

How did you find it?

To be honest, I found it as expected, there were some questions I attempted but couldn't really get, so I ended up sending 5 questions, which I think should mostly be correct, wbu?

I was able to answer 6 fully and did half of 3 questions. I skipped the stats one without even reading it
