Where to begin? The Different route options.

There are two routes to achieve the previously mentioned procedure (in the blog basic steps after Medical education) from anywhere outside Germany:

Learn German in home country. ↓ Learn Medical Terminology in Germany. (Cheaper and generally followed route)	Learn German and Medical Terminology in Germany. (Costlier but effectiver route)
PROS :
Cheaper as learning German is cheaper in home country.	Faster and more focused route if managed properly.
Visa procedure takes upto 3 to 5 months, hence always a good idea to utilize the time and learn as much german as possible.	Language taught by native speaker with proper accent and pronunciation. Always better to learn from a native when you start learning a new language.
You get time to organize all your documents or work simultaneously while learning.	More chance to practice German speaking since you will be using it in day to day life.
Can also hire an online native German speaker to learn the language but is generally costly.
CONS :
Longer process.(May take upto 12-15 months to reach Germany) [Total time 1.5 to 2.5 years]	Costlier to learn and support oneself at the same time (no work visa)
Visa process and documents take time. Might require additional documents.	Adjusting to a new country without prior language skills can be difficult.
