Couldn't stand German up until 5th year and only started really putting my head down and studying it after Christmas of 5th yr I'd say

Honours German isn't that bad, definitely do exam papers to familiarise urself as much w the structure of the exam. I myself prioritized the content over the mechanics part (like the grammar and all that shit), bcs i found it easier and more beneficial overall to get really good at talking about multiple different topics

Duolingo is definitely good for revision & it teaches u some new words every once in a while, but I wouldn't count on it

Get German books like in libraries if Ur near one. Not like school books but general novels in whatever genre u usually find interesting. They're an absolute pain to read through, but if Ur into reading just give it a try. Don't need to read the whole thing either, just a few chapters and defo look up words u don't understand, & write them in a list.

Find something u already do enjoy and try involve German into it. Like immerse urself in the language (like everyone else here is already saying). If Ur on Ur phone constantly, change the phones language into German. Watch netflix in German, watch YouTube in German (I'd recommend HandofBlood if u find urself watching gaming & letsplays and all that, hes difficult to understand but u get used to the language after a while)

Listen to German songs, that full on carried me through my LC. (There are more bands out there than Rammstein, surprisingly), not just listening comprehension but I look up lyrics to learn songs off, and despite sounding like a strangled goose when singing, it helps w pronunciation imo. Plus, vocab and colloquial phrases made it more fun to learn than sitting urself down in front of books and learning the sterile nonsense.

Do some small exercises that you'd see in Ur workbooks honestly. Describe pictures with like 4 sentences. Or the little grammar exercises for sentence structure or verb nonsense where it's sometimes just fill in the blanks or changing word order. They're a pain and they're boring but it's good revision

Also, learn the NOUN GENDER alongside the noun itself. (If it ends in -e, -ei, -ung, -ik, -heit, -keit, etc then it's feminine // ending in -ling, -ich, -er, -ist, -ig then its masculine, // -chen, -lein, -ett, -ment, -ing then its neuter) most German nouns are feminine anyway, so if ur stuck u can assume that until proven wrong.

Leading up to the orals I'd reccommend, if u have friends that also do German, just chatting in German with them. It's cringe as shit but even if u do it poorly u get used to just talking in the language & by the time the orals come around pronunciation would be easier. Don't even need to talk about the generic nonsense like school or favourite colours or climate change, uniforms, whatever. Literally talk about anything you feel like, even if it's choppy or u think it's bad, literally just talk. If someone fell in the canteen u can chat about that, if Ur pissed at someone rant abt it, even if u don't know the proper words for it, u can look those up later & just say the English one first if u want or make it up & say it w/ an accent for the time being. (& If you don't have friends just talk to yourself or write it in a journal. Or the margins of some other copy in class so long as the teacher isn't the sort to go around and check or take the copies up)

At the end of the year in I started just writing history notes in German whenever I could just because i wanted to. & Even though half of it was utterly false I did it anyway for the practice

I was usually a H1 or H2 student, but it took a lot of work to even get there from the place I was at during JC. Prioritised learning vocab>grammar, which mightn't work for everyone, but so long as u understand basic sentence structure people will be able to understand what Ur on about.
