Is the A2 coursework hard to organise if you are a big centre?

No more so than the coursework option of any other specification.

The investigation is only 10% of the A level and needs to be kept in proportion.

There isn't a written test or exam alternative to the A2 coursework element.

Each student should complete a whole investigation themselves, taking the equivalent of two weeks of normal lesson and homework time, this may well be spread over a longer period. Larger centres often stagger when different teaching groups are doing the practical aspects of their investigation.

Every student in each teaching group completes an individual investigation, so that there is no collaboration during the investigation.

A centre with 200+ students doesn't need 200 unique investigations! It is possible for students to do similar investigations if they are in different teaching groups.

Some centres carry out A2 coursework on their field trip.However, large centres may find that it is difficult to find enough different investigations.
