Having a highly accurate predictive model or a complex SQL database means nothing if the executives cannot understand the data. Welcome to the Tableau Data Visualisation practice assessments! Tableau is the industry standard for transforming massive datasets into interactive, highly readable visual narratives.This comprehensive practice test course provides you with 200 realistic, fast-paced questions modeled directly after the official Tableau certification exams and technical BI interviews. Across these four practice exams, you will face direct, scenario-based challenges. You will determine how to build dual-axis charts for predictive house price models, utilise LOD expressions for academic grading metrics, and configure parameters for dynamic mutual fund tracking dashboards.The questions in this course are direct and to the point, testing your actual knowledge of Tableau's mechanics rather than bloated theory. Enrol today and start visualising!Welcome to the Tableau practice tests! Data visualisation is equal parts technical logic and design. This assessment mimics a real-world technical screen, mixing core data architecture (extracts vs live) with advanced canvas techniques (LODs, parameters). Take your time, read the choices carefully, and let's start analysing!Ace your data analyst interview with 200 realistic questions on LOD expressions, dashboards, and data blending.Course locale: English (US) Course instructional level: Intermediate Level Course category: IT Software Course subcategory: IT Certifications

This course contains the use of artificial intelligence.Large Language Models are powerful, but on their own, they lack access to your private data and cannot be trusted to answer reliably. This is where Retrieval-Augmented Generation (RAG) becomes essential.In RAG 101: Build AI Systems with Your Own Data, you will learn how to design and build reliable, end-to-end RAG systems from scratch, with a strong focus on intuition, architecture, and real-world best practices.This course starts from first principles and gradually takes you to advanced RAG architectures. Every concept is explained clearly: not just how things work, but why they work.You will begin with chunking fundamentals, learning how to split documents effectively and how chunk size and overlap directly impact retrieval quality. You will then dive into embeddings, understanding how text is transformed into vectors and how semantic similarity actually works.Next, you will explore vector databases, including indexing strategies, metadata usage, and how modern vector stores power fast and accurate semantic search. From there, you will master the retrieval phase, covering similarity metrics, static and dynamic Top-K strategies, filtering, and advanced techniques such as MMR, BM25, and reranking.You will also learn prompt construction for RAG, including how to combine user queries, retrieved context, and instructions using advanced prompting techniques like few-shot prompting, query rewriting, and guardrails.Finally, the course introduces advanced RAG architectures, including Graph RAG, Multi-Vector RAG, and Agentic RAG, helping you understand when and why to move beyond vanilla RAG.This course is designed for developers, engineers, and technical p

Prepare to pass the PL-300 Microsoft Power BI Data Analyst Associate exam with a focused set of real questions from real Power BI exams. This course is built for learners who want structured exam preparation without unnecessary fluff. You will work through real questions that mirror the style, difficulty, and scenario-based thinking you can expect in the actual certification.Throughout the course, you will strengthen the core skills tested in PL-300, including data preparation with Power Query, data modelling best practices, and building efficient relationships. You will also practise essential DAX concepts such as measures, calculated columns, time intelligence, and optimising calculations for performance. On the reporting side, you will learn how to design clear, interactive visuals, apply filters and drill-through techniques, and deliver reports that are easy for stakeholders to use. Finally, you will cover key Power BI Service topics such as publishing, sharing, permissions, refresh configurations, and workspace fundamentals.Each question includes an explanation to help you understand why an answer is correct and why other options are not, so you learn the logic rather than memorising. This makes it ideal for first-time test takers and for professionals who want to refresh their knowledge quickly.By the end of the course, you will be able to approach PL-300 exam questions with a clear method, avoid common traps, and apply Power BI best practices in your daily work.
