When trying to find resources for Hita in her prep for Physics Olympiad , I found a very interesting and top class resource by Jaan Kalda here.
His documents are highly valuable for all Physics lovers.
Google gives u a mine of resources for a patient and skillful excavator.
I will keep updating about interesting personalities in the field of Physics Olympiads and IITJEE Physics during my quest.
I very much liked his formula sheet here.
