That is what the kids above are doing, in a summer course (click on this post's title) that Christendom College (in Front Royal, Virginia, in the beautiful Shenandoah Valley) offers.
Christendom says its Latin immersion course is "designed to introduce aspiring Latinists to the beauty and power of the ancient language of the Church."
That ancient language of the Church continues to be relevant and necessary today, of course. Learning it well can only benefit anyone who wants to read:
(1) the documents of the Popes and the Holy See in the original Latin and minus mistranslations
(2) the sublime text of the Tridentine Latin Mass
(3) the works of the saints and other spiritually and intellectually great authors throughout history who have written in Latin.
