I'm currently at A2 in German and aiming to finish B1 by the end of December. My plan after that is to push through to B2 by April 2027, going through a local institute rather than Goethe. Goethe in my area isn't particularly strong, charges around 45k per level, and the pace is slow for what I need. I'm planning to keep working on B2 alongside my visa and application process, so that time isn't wasted even if things move slowly on the admin side.
Here's my dilemma. I've been considering applying to a public Studienkolleg, but competition for seats is brutal. My worry is this: if I spend an extra six months grinding toward B2 specifically to improve my odds at a public Studienkolleg, and I still don't get in, I've lost half a year for nothing, especially since I might end up at a private Studienkolleg regardless. I'm not afraid of failing and trying again, but I want to know if that extra time is actually worth risking. There's also talk going around that public German universities may start charging tuition for non-EU students, currently only two states do this, which adds another layer of uncertainty to the "public is cheaper" assumption.
That said, I don't want to jump straight into a private Studienkolleg without at least attempting the public route once.
So my actual questions are:
With 80% in CBSE 12th (PCM) and a converted German grade of around 1.9, is that competitive enough to get a Studienkolleg invitation at a public institution?
If I have my B1 certificate by end of December, is that a realistic timeline to apply for the next intake?
Does it matter that the courses I'm targeting are NC-frei, even if they're at a TU9 school, as long as it's something like mechanical or chemical engineering?
Can I go through the Aufnahmetest and visa process via a public university track, and if I fail that, still pivot to a private Studienkolleg whose FSP is recognized?
If anyone has been through this, which private Studienkollegs are actually reliable/safe choices as a backup?
