Hi,
I'm sorry to hear that you're struggling! Before i give you some tips I just want to tell you, don't freak out over prelim results!!! Many teachers will tell you that prelims are purposely designed to be very hard to give people that don't study as a hard a wake up call! You gave passed all your prelims which is a really good thing! Considering nobody really had any proper exams for the past couple of years teachers are really pumping out on tests and making them hard so students can be put at a better position as many S5s like myself are sitting exams for the 1st time!
So don't panic!
I only do English and maths from ur list but i can try and give some relevant tips for others!
For english; practice doing RUAE. There's not much else to say as there's no content that needs to be revised. Make sure you understand how to answer different question types and reading a good newspaper like the Guardian can help with building vocab. If you need specific help with answering questions u can msg me I'll leave my insta for u!(@narax2801) For poetry since the SQA have revealed what poems will show up in the final exam (check march 2022 revision guide if you don't know already) and find other poems that link well with that poem and memorise a few quotations. Even if you don't fully finish the 10 marker doing the commonalities and extract parts gets you 4 marks plus the other 10 marks on the extract poem will get you to 14/20 which is 70%. Make sure you understand your poems and key themes. Watch some youtube vids on them and use bbc bitesize to help you with this. For the essay make essay plans and recycle quotes wherever possible so you don't have to memorise lots of different quotes and write essays in timed conditions and adapt ur plans to the question (again make sure you're fully thorough with your text use youtube if needed). And write a banger folio.
For maths; PRACTICE PRACTICE PRACTICE! Use the higher maths website which has countless past papers and questions for each topic and if you do a past paper and get stuck on a question DLB maths on youtube has probably done a video on it explaining it fully! Go attend revision classes, do text book questions, online practice questions! Expose yourself to as many different types of questions and keep doing them so you don't forget the basics. If you're struggling, ask a teacher or friend to help you out
I don't do business myself but it is content heavy from what I have been told make flash cards use bbc bitesize to fully understand concepts ask any other friends who may have done it before know your terms!
Physics is similar to maths and requires a lot of practice.
The best way to crack highers is to do past papers!!! Expose yourself to as many questions as possible!
For science/math subjects past papers and practice questions are mostly what you need and for understanding content flash cards and mindmaps should be used then. In terms of revision questions are what you need.
For essay based/ writing heavy subjects have mindmaps, flash cards where content is summarised well and implement with past papers.
All the best!
