Frequently Asked Questions: DASCA SDS
100 minutes for 100 questions — tighter than it looks once hard items start eating minutes. Train the pace now: assign each question a time budget, flag the stubborn ones, and run full timed sessions in the ExamPrepAway engine so test day feels like practice, not pressure.
5 domains make up the DASCA Senior Data Scientist blueprint, led by Machine Learning at Scale (25-30%), Advanced Statistical Modeling (20-25%), Big Data Engineering (15-20%). The weights show where the vendor concentrates its questions — that's where your hours should concentrate too. The complete outline above details every subtopic.
Delivery is automatic: successful payment emails the product to your mailbox within a minute — install on unlimited computers, and if 2 hours pass with nothing (check spam first), contact us. If you fail: sit the corresponding SDS exam within 60 days of purchase, then submit a scanned enrollment slip and official Score Report PDF within 2 days of the exam — full refund, processed within 7 days. Excluded: exams taken within 3 days of purchase, name mismatches between candidate and payer, and free or expired products. Alternatively, exchange for two equal-value exam products free and keep your updates.
The SDS exam is DASCA's official certification exam for the DASCA Data Scientist credential, positioned at the Senior/Expert level. It has never been considered easy — which is precisely why it impresses employers. It also relates to DASCA Certified Data Scientist (CDS), DASCA Principal Data Scientist (PDS).
The enrollment fee is USD 650 — not cheap — and the passing score is 65%. Since the fee applies in full to every attempt, each retake doubles down on the cost. The smarter sequence: drill the 87 practice questions from ExamPrepAway first, book the exam second.
Yes — hesitating is normal, and the free demo exists for exactly that. Download it, get a feel for the DASCA Senior Data Scientist questions, and decide with confidence. Purchases include 365 days of free updates, with new versions announced by email; after expiry, renew at 50% off.
Recommended: Bachelor's degree in a quantitative field, prior data science experience or DASCA CDS certification Rules like these do change — confirm the current criteria on the official exam page (official SDS exam page) before registering.
