Private teaching is more expensive, but it increases your learning. Group sessions run at a slower pace to accommodate students of varying abilities. You might also observe that getting speaking time in a group is difficult, especially when there are kids who prefer to dominate the topic. As an advanced student, one-on-one sessions are the finest and most effective way to study. If you want intensive Spanish language programs, look into institutions in Guatemala that provide incredibly economical one-on-one training.
