Borris I appreciate your evaluation, but I'd like to know how you came to 12,000 students for $50k/month?

By my calculations:

Since PTA gets 50% of the proceeds
$2.50 a month goes ESN from $5 monthly subscriptions

$50000/$2.50 = 20,000 students (monthly subscriptions) a month required i.e. 6 of every 7000 students.

On the X factor side of things a one off $50 subscription for a year gives $50000/$25 = 2000 students (yearly subscriptions) needed a month i.e. 6 of every 70,000 students.

From a pool of 23,000,000 American students this looks likely to be achieved, not to mention Asia (as well as the rest of the world)to pick up the slack.

On another note:

I remember we had Mathletics sessions in high school around 2006/2007 maybe once a week for maths. Was somewhat addictive had different levels from primary school to yr 12. Here's the site: http://www.mathletics.com.au/.
App Annie ranks it in the top 15 educational apps for Australia, attached below is the rank history since release as an app.

Now imagine Kneoworld emulating Mathletics and hitting the top 15 educational apps in the USA..

I'm looking to top up at 0.004 instead of my usual 0.003 now.

IMO DYOR
