If you are a 2017 batch graduating student ,we advise you to take amcat exam before this November and elitmus before February 2017 as companies are starting to recruit 2017 batch students.
Note 1:You cannot retake amcat before 3 months of the first attempt,so if you failed to get good percentile this time you will not miss many companies when you take it again in February.
Note 2: Top 3000 amcat takers of 2017 batch who meet eligibility criteria of mindtree are given a chance to attend mindtree.
Note 3:In elitmus, companies start recruiting 2017 batch students after February so you are advised to learn aptitude well to face elitmus in February.
