pd, congratulatons on your successful oral test, even if you felt you hesitated a lot. As you can imagine, teachers at beginning and intermediate levels are accustomed to that. They also understand that using the right gender is a skill that improves gradually. If the teachers think you did well, you did well! (-:
I am so impressed that you are embarking on learning a fourth (!) language in order to further your studies. That's an ambitious goal, but it sounds as if you're already making terrific progress.
I'm afraid I don't know a source for exercises for the use of articles, either in English or in German, aimed at native speakers of languages without articles. (Russian is apparently another, but I assume you don't want to learn Russian just to learn German. (-; ) Maybe others in the forum can give you some tips on articles in German.
One source I often recommend to students seeking practice with academic writing in English is the Online Writing Lab (OWL) at Purdue University in the US. (A historic engineering school, as you may know.)
Here's their page on articles, in case it helps as part of your review.https://owl.english.purdue.edu/owl/resource/5...
However, it's pretty basic, so I suspect you would benefit more from a more advanced English grammar.
OWL Purdue also has many useful tips about English grammar, punctuation, academic writing, citations, bibliographies, and so on; you might enjoy just browsing there, if you're not already familiar with the site.
Another option might be the Crossover Chat thread in the LEO forum. Siehe auch: Crossover Chat #336
You, O fortunate person, could write in either English or German or both, just to practice and for fun. We understand if you may not have time for such frivolity, and we may be mostly a bit older than you. But I will say that by practicing there over the years, I have learned the gender of many German nouns -- after I looked them up so many times that eventually I didn't have to look them up quite as often.
