Study group discussion
Discuss reading or problem sets with a small study group — explain, listen, and build on others' ideas.
What makes this one hard
Group talk is overlapping and unfinished — people interrupt, ideas arrive half-formed — so the skill is entering the conversation rather than waiting for a gap that never comes. English has low-cost ways in, and they have to be automatic to be useful.
