Quick Read

• Mahesh Darekar, a former UK IT professional, cleared the NISM Series XV exam in his first attempt with 77%, after just three weeks of preparation
• He skipped the official NISM workbook and audiobook, finding both too theoretical, and switched to a structured mock-test-driven course instead
• Ratio confusion (ROE vs ROCE) was his biggest early struggle, solved by printing and pinning a ratio cheat sheet on his wall
• Case studies now carry 20 marks (up from 8), making them impossible to skip; 3 of his 5 exam case studies matched course material almost exactly
• With 72 seconds per question and negative marking in play, he advises skipping unclear questions rather than guessing
• Non-finance background candidates should add 15 extra prep days beyond the standard three weeks

Part 1: Cracking the NISM XV Exam Strategy That Actually Worked

Mahesh decided to pursue the NISM Series XV Registration Eligibility exam to formalize years of hands-on trading experience with structured fundamental knowledge. The curriculum covers terminology, company analysis, balance sheets, cash flow statements, and even DCF valuation models—areas he admitted he had never studied despite years of active trading.

His first attempt at preparation was the official NISM workbook, which he found too boring to maintain focus for more than 30 minutes. He then tried an audiobook version, which felt too robotic, before eventually turning to a structured video course after searching YouTube. This shift from passive reading to a structured, test-driven course became the turning point in his preparation

Three resources stood out in his prep routine:

• Chapter-wise mock tests after every lesson, treated as non-negotiable before moving to the next chapter
• One-liner revision notes covering key concepts, called genuinely helpful for quick recall
• A printed ratio-analysis cheat sheet, stuck on his wall specifically because he kept confusing similar metrics like ROE and ROCE during early preparation
• He also built his own error-tracking system: whenever he got a mock-test question wrong, he logged it in a separate sheet and reviewed those specific mistakes the next day before starting a new chapter.

Time Investment and Chapter Priorities

Mahesh dedicated one to two hours daily for three weeks, without disrupting his regular trading routine. Weekends were reserved specifically for the heavier, high-weightage chapters, particularly Chapters 8, 10, 12, and 1415, since these carry more exam weight despite sometimes having less video content. His advice for non-finance candidates was to add at least 15 extra days to this timeline, since financial terminology and statement-reading conventions take longer to internalize without a commerce background.

Case Studies Are No Longer Optional

A major shift in the current exam pattern is the case-study weightage, now worth 20 marks compared to 8 previously, which means candidates can no longer skip this section. Mahesh prepared entirely from his course's 13 case studies and noted that three of the five case studies in his actual exam were nearly identical to ones he had already practiced, just with different names and numbers.

He did flag one exam-day surprise: one case study's balance sheet was so long that it required scrolling across two or three screens, something he hadn't anticipated and that cost him valuable time. His practical tip here is to jot down key figures on a rough sheet of paper rather than repeatedly scrolling back and forth.

Time Management and Negative Marking

With roughly 72 seconds per question across 100 questions and negative marking in play, Mahesh emphasized that skipping 8 to 10 genuinely confusing questions is safer than guessing randomly across all of them. He personally attempted 99 of 100 questions and cleared the exam confidently on his first try.
