You can check the latest cost on Pearson Vue. But for me for each part the cost was USD 125 that means approximately between Rs 5500 to Rs 7000. I do not know the exact cost for the mandatory training so cannot comment on that. So excluding the mandatory training part the cost for all 3 exams could be around Rs 18000.
God, this has become expensive. Just checked the oracle website and I see that the minimum cost of training is Rs 13888. Hence, total cost is about 30K+. This is really sad to hear that the company is focusing on profit making. This is a real dampener for aspirants, like me.
