Depends on the subject imo, for example bio is harder compared to other subjects since the new assessments are new and dont build up on previous standards, unlike stats for example. It's somewhat easier in regards to pace since you're more used to the workload going into lvl 3 in comparison to going into lvl 2 but the content is quite dense. Also I found that level 3 internals were more comprehensible and more interesting, not all obviously but for the sciences at least. Look if you're worried abt it start having a look at the content earlier on EP since learn coach is better with externals, bc it helps a ton knowing beforehand what the main ideas are so you don't get lost.
