Sorry for all the stops and starts.

As I mentioned, this is all very impromptu

and very improvisational, but yes,

now even this dashboard that I'm using

says that I'm online on at least Facebook and YouTube.

So I will just keep going and power through this

because I think there's a little bit of a delay

between when I'm starting and stopping.

So it's I'm pressing start, it starts,

and then everyone says it's working,

but then by that time I thought it wasn't working

and then I started again.

But I think we're good, I'm just gonna

keep powering through this.

I'll start over.

This, for those of you all who are wondering where I'm am,

I'm in a walk-in closet off of my master bedroom

because out here in California we have these

stay in place orders, and as I mentioned,

this is the walk-in closet

where Khan Academy all got started.

I have spent a year in this walk-in closet back in 2010,

so I'm prepared to spend at least many weeks

or months in this walk-in closet if necessary.

But as you can imagine, a lot going on.

For those of you that this is the first time

that you're coming to this livestream,

the whole point of it is we obviously

have these mass school closures going on

and we, at Khan Academy we find ourselves

in a somewhat unique situation of realizing

that this is what Khan Academy to some degree was made for

even though we've never really thought

of this circumstance actually happening.

And this is clearly a very, situation,

I don't think anyone would want this,

the ideal circumstance is that the schools are open,

Academy is somehow a substitute for live experiences.

We've always imagined them being in partnership

with incredible teachers and classrooms

and you have your peers and you can liberate the classroom

to then go to higher order tasks.

But we've also imagined Khan Academy

being used in parts of the world

where students might not have access to school

or might not have access to certain,

to instruction or curriculum material of certain qualities.

And we now find ourselves in a situation

where most of the world is going to find ourselves

in that second category.

So a couple of things are happening.

I've been taking questions from parents,

teachers, students, I would love

to get more student questions actually,

I know there's some concern about the cancellation,

delays of some of the SAT administration tests.

On Friday, we released some schedules

for students of different ages,

and one thing that we recommended for sure

for high school students is to

use our official SAT practice.

Obviously you can use us for math.

You can use us for the sciences,

you can use us for the social sciences,

but we also have the official SAT practice

that we partner with the College Board on.

And even if you aren't taking the SAT

or even if now your SAT has been delayed,

I encourage you to think about using that

because it covers math, reading, and writing,

and it'll really make sure that those skills don't atrophy

even if you aren't taking the SAT any time.

And if you do end up taking the SAT in the next three,

four months, it'll be real useful.

But what I would love to do is make this as interactive

as possible, I'd love to take questions from all of you.

I see, let's see if I can scroll down here.

I got a question, I'm a foreign student

who's aiming for a mathematics course in the USA,

what courses exactly should I examine in Khan Academy site?

Are linear algebra and multivariable calculus needed

and what tests I need to take?

Well, Muhammad, it depends what level

you're coming into the United States.

I just saw a comment that Sal is getting old.

We all get old.

It depends what level.

If you're coming at the college level,

you would probably have to take something

like the SAT, there might also be things

like the TOEFL which is measuring,

I think it's Test of English Language Fluency

or Fluency Language, something like that.

I forget the acronym.

But for those tests actually the level

of mathematics you need is not overly advanced.

For the SAT, you really, the level of math,

you really have to master algebra two,

and know it well, there's some tricky questions on there,

but for the most part they're algebra two questions.

And similar for the reading comprehension level.

Things like linear algebra or multivariable calculus,

which are typically a freshman or sophomore level course

in college in the United States are definitely not required

for entry level into college.

Obviously if you're thinking about graduate studies,

linear algebra's especially tends to be applicable

in a lot of the technical fields.

Let's see, other people are asking questions.

Is Khan Academy in Mountain View closed as well?

Yes, we have shut down the office.

It's actually by law now, unless you work

in our area at a healthcare facility or a grocery store

or gas station, something that's considered essential,

they are telling folks not to go to work.

All right.

So hi Sal, I'm a, this is from Basil,

hi Sal, I'm a 17-year-old high school student

and I have been teaching for around three years

for physics, chem, and math, do you recommend

any sources to improve someone's ability to teach?

That's a great question, I've never had quite that question.

Think the number one thing is really mastery

of the material yourself.

I think even for myself when I first learned

a lot of that material in high school and college,

I was a good student and I understood it quite well,

but it would be great if,

when I started doing Khan Academy, it would,

and sorry, for the team, all these Slack questions

are coming across and it's making it

a little bit disruptive.

I'll look at the iPad in a second.

But to learn how to may be practice teaching better,

obviously there's nothing like teaching itself.

I highly recommend trying to make resources

that cover that material and I think you'll find

that you'll learn the material a lot deeper.

Let's see, I'm gonna go to the questions

that the team is looking at.

Okay.

And so I'm looking at the doc, team.

And so I'm looking at the top of it.

So, yeah, and what's going on right now

is our team is looking at the various streams

and then they are curating the questions

for look at, at this iPad, so there's a lot

of home brew things going on here.

But I'm happy to continue to answer questions.

I will look at the stream that I see on this dashboard

and see what other questions people have.

Let's see, people have asked,

it seems like the quality is subpar, my apologies for that.

I will try to, before tomorrow,

try to find a place in the house

that hopefully has better quality Wi-Fi.

I have four full bars here, but I guess

that's not doing the trick.

This is my first day that I'm doing this at home,

so it'll hopefully get better every day.

So please ask any questions, the team is looking at it,

they will update this doc that I'm working from.

I don't see any of the questions just yet.

So one question J.R. Gilroy asks,

will you be leading a nationwide SAT, ACT study session?

A great question, J.R., we, as part of our effort

to support everyone, we are thinking about things like that.

As you can tell, even for this livestream

we're trying to figure out the technology,

but I hope that over the, especially if this school shutdown

situation is protracted, if it keeps going,
