The quiz should be closed.

I have a couple of announcements.

We've decided that we're going to make the quizzes public for practice.

We have these practice questions that I'm sure most of you have seen.

So we're going to add the quiz questions, the Tuesday quiz questions for that.

So that is probably a very good resource for practicing before the exam, after the semester.

To make this more attractive, more of an incentive, we're going to use one of the quiz questions

and one of the homework questions, verbatim, in the exam.

So it might be a good idea doing the homeworks and the quizzes again for practice.

We're also going for the homework questions.

We're actually working on a peer grading platform in Aliyah, which means you can actually submit your homeworks

or the old exam questions to your peers for review.

Your peers would be grading them, which is not necessarily the same as the graders for the exam will do,

but we'll give you the same resources we have.

I would ask you to actually volunteer helping out your fellow students by grading their stuff.

Chances are very good if you are actually grading other people's homeworks, you're learning more than they do.

It is well known that among teachers, if you really want to understand something,

you can either write a book about it, then you understand what you're talking about,

or give a course about it and do the grading and exams, then you also know.

I've learned most of my AI outside my research area by teaching it.

Back when I started, AI looked quite different.

That's exam preparation.

I'm expecting that the Aliyah system might become quite useful in that.

We are also going to make, probably next week sometime, an Aliyah survey about the things you want to say about the system.

To give you incentive of doing that, we're going to count a fully completed survey as one Tuesday quiz.

We're not grading the survey, of course, so it will be 100%.

Which, from looking at the results, many of you could use.

Any questions?

Yes?

How many exams have you prepared for?

All of the exams I've prepared over the years, and I think that's at least 14, are online.

So you can see exactly what past exams were.

They will be different, but not very different in spirit and in difficulty.

You can imagine that younger exams are better predictors than older exams.

We're learning how to do it as well, especially with more students.

I had 50 students when we started.

Depending on how you count, it's between 500 and 1,000 now.

So grading became different.

But preparing for the old exams and being critical with yourselves is a very good predictor.

That's why we do the peer grading, because it's easier to be critical with somebody else than being critical with yourself.

More questions?

Oh, by the way, somebody asked about a cheat sheet. We've decided against that.

There's too much chaos produced if we want to check all of them for the whole menza full of students.

Righto.

Questions?

Okay, so let's get back to planning.

Remember, planning is essentially logical inference.

Or logical inference plus time and change.

That's one way of looking at it.

Or general problem solving via search with a capital G in the general.
