Based on the evaluation results I received, it seems that the proposal was rejected because it was too expensive to fund, not because of the scientific merit. The academic aspects were all highly rated. That's why I think that submitting a project for six months would increase my chances of getting the grant.
I didn't find on the website any information about how long the course lasts.
5 changes but I can't show you them in bold on this forum - you'll have to check my revised text in detail. Kind regards, Michael
