Personally the Air Law and Operational Procedures exams are an improvement.
The Ops procedure exam is more relevant and covers what I think is practical stuff.
at least they have moved away from asking questions about things hanging from masts.
Nav is a disappointment but in EASA places where UTC is some time away from local time I can see the relevance.
If schools have not modified their ground school then they should not be letting students sit the exams until they have done so. Sending someone into an exam with only 80% of the knowledge is neither smart nor fair.
The challenge is about getting the study organised into chunks so small groups of exams are organised into sittings. Maybe trying to get them done in 4 sittings and having a couple of sittings spare just in case.
