How should I study for IT Passport?(or any other profiency tests held in japanese that are not language related)

I need to pass IT Passport, which is the most basic level of testing in Japan regarding IT things.I passed N1 this year and I used to imagine that I wouldn’t struggle so bad with if when my japanese got to this level.I’m posting this because I really don’t know what I to do.

I haven’t previously study 80%-90% of what is going to be on the test in English or in my native language so I’m having a hard time learning and retaining the information of things that are complex, because they have long words full of kanji that I don’t recognize or that I find very difficult to remember.

I wanted to learn it directly in japanese,if possible, but I found no pre-made Anki flashcards or other resources that will help me keep the information.

Do you have any tips? Resources?Should I just learn it in English and then learn how to say it in Japanese?

If you have studied for the nursing test or other specific profession related proficiency tests that are held in japanese, please share your experience!
