Taxation Law Mock Test - A Reality Check

I took this mock test last semester, and I must say it was an eye-opener. I managed to score 72/100, which is a decent score, but I was expecting more. The test had 50 questions, and the duration was 60 minutes. I was asked about the Income-tax Act, GST laws, and TDS. I found the questions on exemptions and deductions tricky, which is why I scored low (14/20). One question that really puzzled me was: "What is the provision for claiming relief under Section 89 of the IT Act?" I blanked out, but then I remembered our professor, sir, mentioning it in class. Anyways, I'm planning to revisit my notes and get some practice questions to improve my weak areas.
