Neo4j Graph Data Science Practice Test

The Neo4j Graph Data Science Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. Exam-style practice for Neo4j Graph Data Science (GDS) for data scientists and engineers — graph fundamentals (nodes, relationships and Cypher), the GDS library and graph projections (the graph catalog and in-memory projections), algorithms (centrality, community detection, pathfinding, similarity and embeddings), and machine learning pipelines and operations. Written to the Neo4j GDS and Cypher documentation for 2026. Score 70% or more on its 20 questions to earn a verifiable Neo4j GDS Exam Preparation certificate (SOA-NGDS). Every question is based on published standards and research — including Neo4j Graph Data Science library documentation (Neo4j), Neo4j graph database concepts (Neo4j, Inc.), Neo4j Cypher query language manual (Neo4j) — and each answer is explained with its source.

Yes. Science of Apps has a free Neo4j Graph Data Science Practice Test built on the current Neo4j exam outline for 2026 and 2027. It covers graph fundamentals, GDS library and projections, algorithms and machine learning and operations, scores you instantly and issues a verifiable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Neo4j GDS Exam Preparation certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Neo4j Graph Data Science library documentation (Neo4j); Neo4j graph database concepts (Neo4j, Inc.); Neo4j Cypher query language manual (Neo4j). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Graph Fundamentals (Nodes, Relationships and Cypher); GDS Library and Projections (Catalog, Projection and Memory); Algorithms (Centrality, Community and Pathfinding); Machine Learning and Operations (Pipelines, Features and Ops). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Data scientist or analyst, Graph data engineer, ML engineer using graphs, Neo4j developer and GDS certification candidate. It suits anyone who wants a quick, verifiable way to show Neo4j Graph Data Science knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

GDS is a Neo4j library of graph algorithms and machine learning tools. It runs algorithms like PageRank, community detection and pathfinding, plus node embeddings and ML pipelines, over an in-memory projection of a graph, to find patterns and features in connected data.

A graph projection is an in-memory, analytics-optimised copy of part of your Neo4j graph that GDS algorithms run on. You project selected node labels and relationship types into the graph catalog, run algorithms efficiently, then write or stream results back.

No. It is an independent practice test written to the publicly available Neo4j Graph Data Science content outline for 2026 and 2027, for checking your readiness before you book the real exam. Passing earns a Science of Apps certificate rather than the official credential.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
