IMS SimTests set a great benchmark for how the real test would be. The mock tests helped me figure out my exam strategy and apply it in different test like conditions. IMS gives you the option for mocks not only on mainstream tests, but also on relatively new and unknown tests like IIM Calcutta - PGDBA and IIFT! The help provided by IMS for the GD PI process, all of which was customised for each institute, is invaluable! A big thumbs up to IMS!
