Yes, and we encourage it. A free PDF demo of the GB0-520 questions is available so you can evaluate the quality and layout before buying. After purchase, your material stays current with 365 days of free updates — and if that period ever expires, you can extend the update service at a 50% discount through your member zone.

You will face 60-70 questions within a time allowance of 90-120. Raw numbers aside, the real skill is pacing: candidates who run out of time usually spent too long on early questions. Our advice is to set a mental per-question budget, skip and revisit anything that stalls you, and complete at least two full timed runs in the Actual4dump test engine before the real appointment so the clock never rattles you.

Both situations are covered. Take the corresponding GB0-520 exam within 60 days of purchase without passing, and you may claim a full refund under our 100% Money Back Guarantee: submit a scanned exam enrollment slip plus the official Score Report PDF within 2 days of your exam date, and we finish processing within 7 days. The conditions are strict — an exam taken within 3 days of purchase does not qualify, the candidate's name must match the payer's, and free materials or expired orders are excluded.
