für eine Prüfung lernen

You will usually see the verb lernen conjugated at the second position in a normal sentence. For example, Ich lerne heute. If you have a modal verb like müssen (must), lernen moves to the very end. It is a very flexible phrase. You can add adverbs like fleißig (hardworking) to show off. Just remember that the preposition für always takes the accusative case. Luckily, eine Prüfung stays the same in accusative as it is in nominative.

Use this anytime you are in an academic or professional certification setting. It works for school kids, university students, and adults taking a driving test. Use it when a friend asks you to go to a party but you have a math test tomorrow. It is a perfect excuse to decline an invitation. You can also use it in a professional context if you are getting a new certification. It sounds responsible and serious.

Do not use this for casual hobbies. If you are just reading a book about history for fun, you aren't für eine Prüfung lernen. Also, avoid using studieren here unless you want to say you are majoring in 'Exam-taking.' If you are just doing your daily homework, use Hausaufgaben machen instead. This phrase implies a specific, high-stakes goal at the end of the tunnel. Don't use it for a tiny quiz; that's usually just a Test.

Germans take their exams very seriously. There is even a specific word for exam anxiety: Prüfungsangst. Education is highly valued, and the 'Prüfungszeit' (exam period) is a sacred time of silence and focus. Libraries are packed, and the 'Mensa' (cafeteria) is full of tired-looking students. If you tell a German friend you are für eine Prüfung lernen, they will likely respond with 'Viel Erfolg!' (Much success!) and leave you alone to focus. It is a culturally respected state of being.

If you want to sound more like a local, you can use slang. Büffeln is a popular way to say you are studying hard, like a buffalo. Another one is pauken, which sounds like beating a drum. These are great for informal chats. You might also hear sich vorbereiten (to prepare oneself), which is a bit more formal. If you are doing it at the very last minute, you might call it Bulimie-lernen—cramming everything in just to spit it out on the paper.
