Both our general intensive courses follow the same methodology and materials, the only difference between them is the number of hours per week and day, which is the aspect students must take into account when deciding the one they prefer based exclusively on how much time they are willing or available to commit to classes:

Intensive: 10 hours (2 per day) from Monday to Friday (5 days)
Intensive+: 20 hours (4 per day, break included) from Monday to Friday (5 days)

Intensive+ courses include an additional session each day for some extra practice which might be especially helpful for those students who may not have many opportunities to use Spanish outside the classroom or that could need a boost. They will definitely help to build a more solid base, but not necessarily to learn more or progress faster.
