If you used Clearing in 2024, how did you find it?

I have no idea on how to study (YR13->UNI)

I'm currently a year 13 student doing a couple BTEC's (Applied Science, Business, PEBTEC; Physiological and Coaching) I achieved a merit in PE through simple notetaking, though I gained more poor grades in my other lessons, teachers and students think I'm doing well but I have virtually no idea on how to study effectively or study for them, Some of my classmates are easily able to breeze right through the tests and exams but I sit here dumbfounded at every opportunity.

I've tried many ways such as applying the 20%/80% rule (Finding "gold" in information as a metaphor etc) but it just slips out of my mind and my negative mindset kicks in; causing lots of distractions to attract me.

At this point, I've watched many hours of "How to study" videos along with lots of my money gone into school equipment/house equipment to let me study easier but I just don't know how to. My mum has high hopes and supports me going into uni but I feel like I'm not going to able to achieve a spot in my ideal university.

Any sort of advise, tips and tricks would be plenty useful.
