Answer 1

Without knowing exactly what you are wishing to learn try these searches.

"Free (topic) training"
"free (topic) help"
"internet (topic) training"
"internet (topic) tutorials"
"free (topic) tutorials"

"free (topic) e-learning"
"online (topic) training"
"online (topic) learning"

so on so forth

of course replace (topic) with the subject matter you are seeking.
