Welcome! I am just halfway through my Social Psychology BA program :) This book has been extremely helpful for writing research papers. Also, powerthesaurus.com., grammarly and online APA citation generators. After writing so many academic research papers, choosing fresh language and sentence flow can become tiresome. Even after you get the hang of citation formats and paper organization, it’s just nice and handy to have those little helpful tools! You will do great!
Use an academic phrasebank - or even better, make your own.
A phrasebank is a list of ways that professionals say various things...how they say who was in the participant pool, how they say that two groups were the same, and so on. You can find them online or buy a book of them.
The cost-to-benefit ratio is excellent.
I recommend The Only Academic Phrasebook You'll Ever Need: 600 Examples of Academic Language to my undergrads. It's in American English. This website is a phrasebank in British English.
I’ve found this book to be really helpful during my studies!
