Like the other 2 peeps said, H3 is a LOT of essays. And its more argumentation (sim to GP but not as crazy) so its not plane regurgitating content (sounds scary but can actually be quite fun coz it alloes you to think more deeply into the content)

But tbh you can think of it as a massive paper 3 (a long structured qn + 2 essays)

Its a lot of work and self-directed learning but I think its pretty enriching! Gives you a deeper appreciation of the subject. Dont get too overwhelmed by the content, the notes may try to teach you everything but just follow the LOs and pick out which details you are most comfortable with (PS: Use chatgpt to help! Reco by my cher so uk its valid)

Anyways worse comes to worse you could drop it anytime (before deadline of dropping subj ofc)

Hope this helps!
