in the part "energy change - potential energy", there is a mistake in the derivation:  Theta = 2h/x = L/x The last part should be x/L

Thanks for mentioning this, Mat. It looks okay for me (Chrome, Firefox, Safari) right now, but I have seen sporadic issues for one reason or another. Could you reach out to me by email ([email protected]) if the symbols still aren't rendering...

Hi David! You're right, there's some missing pages here. Maybe they got lost in the site reorganization over the summer. I'll try to find (or recreate) them as soon as I can. For now, there's some teaching ideas on the Unit Plans sites for these topics:...

Hey Jane, check the menu on the left for the ready-made IA ideas. They all start "Optional Practical". I'll get this page cleaned up and easier to read shortly!

I didn't see any ready made IA ideas? Nothing is here?

Special characters in the text (symbols, subscripts etc.) not displaying on a Chrome browser. Seems to work in Safari though.

Esta sección me aparece incompleta. No veo información de las temáticas. ¿Me pueden ayudar con eso?

You are absolutely right. I haven't gotten to this unit yet with my DP2s, but I'll try to get a new test put together ASAP. Thanks so much for flagging this! Update: I've written and uploaded a new test.

I think Q2 needs to be replaced - transformers don't seem to be mentioned in the current physics guide.

Yep! The new course guide is on MyIB. There is a new login procedure over there, so you'll need to create a new account using your previous email address.
