I had enrolled for the SimCAT Proctored test series by IMS, and the experience has been fantastic. According to me, attempting mock tests is one of the best approaches to CAT preparation. Of all the mocks I took, the SimCATs were definitely the closest to CAT 2017. Along with quality questions, the proper explanations made it a value adding experience. Also, support from administrators at the local center has been quite generous. Thank you to IMS!
