Is certification in data structures useful after an MCA?

Data structures help students organise information efficiently and are important for writing scalable programs. Arrays, linked lists, stacks, queues, trees, graphs and hash-based structures are common foundations. This makes data structures more valuable when it is supported by hands-on practice and a clear explanation of what you built. This point is specifically relevant to the data structures aspect of MCA study. For this specific question about data structures, the practical takeaway is to relate the concept to your own MCA learning goal.
