Hi Harshit and Nishanth -

The Techniques Trainer is an experimental feature. We launched it specifically for Algebra and Number Theory people who are Levels 1 - 3, to see if users would find it useful and to figure out how much work it takes to write the summary pages (like this one).

That is why you both (and many others) are not seeing it on your homepage... yet :)

I became level 4 in Algebra and Number Theory this week. Does that mean I'd lose the trainer when the next problem set kicks in?

Is there a technique trainer for Physics? If yes, then why am I not seeing it despite of being in level 3?

Hi Sambit,

There isn't a technique trainer for Physics... yet :) If people use this feature often in Algebra and Number Theory, we will consider adding it for physics as well.

Hmm I just noticed this. How can I find this on my home page? I just seem to have stumbled upon it as a result of noticing it on somebody else's profile.

It's on the main page of "challenges" in the same column with Number Theory and Algebra,just above the button "Start/Resume"

The swimming pool that Calvin goes to has dimensions 20 meters long, 8 meters wide and 3 meters deep. What is the volume of water (in m3) that the swimming pool contains?
