In a word, “No.”
Four hours a day of learning Italian is more than enough for most people.
There is, after all, a limit to how much Italian your brain will be able to absorb on any given day.
And there’s more to life than studying, no?
In the afternoon you could do tourist stuff, or hang out with new friends from your class and speak Italian.
If that doesn’t sound serious enough, there’s also a tutor available a couple of hours each afternoon (not Fridays) to help you with your homework, or to give extra speaking practice.
So why pay extra for a couple more hours of lessons in the afternoon?
Unless, maybe, you’re swotting for an up-coming exam.
Or you’re a diplomat, brushing up on your Italian before taking up a new post at your country’s embassy in Rome.
In which case, they answer would be, “Well, if you really must.”
Most people, though, are best off signing up for our standard 20-hour per week, Italian course.
That’s four hours of lessons each morning, from Monday to Friday.
More than enough to keep you busy and ensure you make excellent progress with your Italian.
Up to you, though.
