Do I need to do well on the assessment test to get selected?
Generally, you should be able to score above 30% in the assessment test to even prepare for IBA. Otherwise, it's very risky for you, and you should prepare for something else where you'll have a better chance. However, the batch applications are reviewed based on the answers to the application form, not the results of the assessment tests. Taking some assessment tests is still mandatory tho. We want to make sure that everyone's getting an idea about the question paper and evaluating their compatibility before they jump in.
