When it comes to learning new skills quickly, "crash courses" are often a popular option. However, there are other terms that can be used to describe these intensive, accelerated learning programs. One alternative is the term "intensive courses," which highlights the idea of concentrated learning in a short amount of time. "Accelerated learning programs" is another alternative that puts emphasis on the speed of the course. "Boot camps" is a popular term used to describe intensive courses in technology, business, or other fields. "Intensive workshops" or "immersion programs" are also terms that can be used to describe crash courses. No matter what term you use, the goal remains the same: to learn a lot in a short amount of time.
