| KHAG L | No. 124 - OCTOBER 2020 | 09 spanned a range of students were in the course of their PhD, and most of the others were doing Masters' degree. This is a change from the previous schools, where Masters' students were very few, reflecting very good applications by a number of very young students.As usual, therewas a good balance of the genders. The lecturers were from CRAL (3), IUCAA (2), and UK (Liverpool, 1), and the tutors of the five projects were from CRAL (2), IUCAA(2), and UK (1). The lectures andmost of the projects were carried-out using Zoom. This worked fine, and the usage of the "breakout" rooms, where the full audience could be redistributed (randomly) in small rooms or tables. The "tea breaks" and the school dinner helped to establish social exchanges in a format finally close to a real physical session. As usual, the students were self-organising off-school evening session, where they presented their own research work, or addressed subjects of concern to them. The projects presentations were great. All the projects achieved remarkable results. We requested the participants to fill an anonymous feed-back form at the end of the school. It seems that 90% of the students found adequate balance between the lectures and the projects, and the other 10% would like to increase the time for the projects. We also asked a question about their environment during the lockdown. 76% of the students informed that the seminars, and journal clubs continued in their home institute during the lockdowns, but 55% mentioned a clearly negative effect of the lockdown on their work. Finally, 95% of the students thought that we should make IFAS – 7, even if travel andmeeting restrictions persist. The school went beyond our expectations; the remote organisation did not affect the quality of the achievements. We mostly feared for the cohesion and social exchanges, but hours of time zones. Themajority of the we felt that finally it went remarkablywell. The directors of the school were: Philippe Prugniel (CRAI, France), and Kanak Saha (IUCAA). The IFAS– 7 has been planned in IUCAA, tentatively during July 29–August 6, 2021.
