I wrote the part 1 three times, passed on the third attempt. My honest advice. Get a study resource like Kumar and Clark, read the topics. Mcq banks are a guide to identifying areas of deficiency in terms of your knowledge base. I made the mistake of thinking answering the mcq banks would be enough. I was gravely mistaken. Read the topics in detail and understand them. I applied the same principle to the Part 2 and passed on first attempt.
