14.3 Final Study Plan & Practice Assessment Strategy
Key Takeaways
Prioritize final review by combining diagnostic weakness with official domain weight — Infrastructure (30-35%) and Identity/Governance/Monitoring (25-30%) deserve the most repair time when scores are low there.
A concrete 14-day plan (domain gap-repair days, then two full timed mixed runs) outperforms even re-reading of all 14 chapters.
Microsoft's official free practice assessment is a useful independent calibration check against the OpenExamPrep timed mixed-domain runs before booking the real exam.
AZ-305's ~60 questions in 120 minutes works out to roughly 2 minutes per question; use 30/60/90-minute pacing checkpoints in every timed practice run.
Don't schedule Pearson VUE until you consistently score at or above roughly 80% on both the OpenExamPrep bank and the official Microsoft practice assessment.
Why a structured final plan beats unstructured cramming
By the time you reach this chapter you have worked through all 49 official AZ-305 objectives across 12 functional subgroups. The temptation in the final one to two weeks is to re-read everything evenly, or to keep re-reading whatever chapter you personally enjoyed most. Neither approach matches how the exam is actually weighted: Infrastructure carries 30-35% of the exam, Identity/Governance/Monitoring carries 25-30%, Data Storage carries 20-25%, and Business Continuity carries 15-20%. A final plan that ignores these weights risks spending three days polishing a domain worth 17.5% of the exam while the domain worth nearly a third of it gets a single evening.
Step 1: run a domain-filtered diagnostic pass
Before building a day-by-day plan, take the OpenExamPrep AZ-305 practice bank in domain-filtered batches — one pass through the identity/governance/monitoring category, one through data storage, one through business continuity, one through infrastructure — untimed, ideally right after finishing all 14 chapters of this guide. Record your raw percentage correct per domain in a simple table like this:
| Domain | Official weight | Your diagnostic score | Priority |
|---|---|---|---|
| Infrastructure | 30-35% | (your %) | Priority 1 if below 80% |
| Identity, Governance & Monitoring | 25-30% | (your %) | Priority 2 if below 80% |
| Data Storage | 20-25% | (your %) | Priority 3 if below 80% |
| Business Continuity | 15-20% | (your %) | Priority 4 if below 80% |
The priority column is not simply "lowest score first." A domain that is both heavily weighted and weak (for example, 65% on Infrastructure) deserves review time before a domain that is lightly weighted but equally weak (65% on Business Continuity), because fixing the same percentage-point gap in Infrastructure is worth more raw exam points.
Step 2: a concrete 14-day final plan
| Days | Focus | Activity |
|---|---|---|
| 1-3 | Infrastructure gap repair | Re-read only the specific Chapter 10-13 sections tied to your diagnostic misses (compute, application architecture, migration, network); redo those question-bank items |
| 4-6 | Identity, Governance & Monitoring gap repair | Re-read only the missed Chapter 2-4 sections (logging/monitoring, authentication/authorization, governance); redo those items |
| 7-8 | Data Storage gap repair | Re-read only the missed Chapter 5-7 sections (relational, semi-structured/unstructured, integration); redo those items |
| 9-10 | Business Continuity gap repair | Re-read only the missed Chapter 8-9 sections (backup/DR, high availability); redo those items |
| 11 | Full timed mixed run #1 | Complete a 60-question, 120-minute timed run spanning all four domains at real exam pace |
| 12 | Targeted review | Re-read the exact section behind every miss from Day 11 — do not re-read whole chapters |
| 13 | Full timed mixed run #2 | Second 60-question, 120-minute timed run; target 80% or higher before proceeding |
| 14 | Light review + logistics | Skim key takeaways only, complete Microsoft's official free practice assessment, confirm exam-day logistics, rest |
Step 3: use Microsoft's official free practice assessment as a calibration check
In addition to the OpenExamPrep question bank, Microsoft Learn offers an official free practice assessment for AZ-305, delivered through an assessment partner. It is calibrated to reflect the real exam's difficulty and gives feedback by skill area rather than a single number, which makes it a useful second opinion on whether a domain you scored well on internally is genuinely exam-ready. Do not schedule your Pearson VUE appointment until you are consistently scoring at or above roughly 80% on both the OpenExamPrep mixed-domain timed run and the official Microsoft practice assessment. Scoring well on only one of the two is a signal to keep practicing, not to book the exam.
Step 4: pace your practice runs like the real exam
AZ-305 typically presents around 40-60 scored questions in 120 minutes, which works out to roughly 2 minutes per question on average if the count lands near 60. Use checkpoints during your timed practice runs so pacing becomes automatic:
| Elapsed time | Questions you should have completed (60-question run) |
|---|---|
| 30 minutes | ~15 questions |
| 60 minutes | ~30 questions |
| 90 minutes | ~45 questions |
| 120 minutes | All 60, with time to review flagged items |
If you are meaningfully behind a checkpoint, flag the current question and move on rather than spending eight minutes deriving a single answer — a flagged question you return to with 20 minutes left is recoverable; 15 unanswered questions with two minutes left is not.
Common final-week mistakes to avoid
- Over-indexing on vocabulary flashcards while neglecting scenario-judgment practice — AZ-305 tests trade-off decisions, not term definitions alone.
- Skipping hands-on labs in the final week because "there's no time" — even 30 minutes configuring a real failover group or NSG cements a concept far faster than re-reading it.
- Never timing a practice run until exam day itself, so pacing anxiety becomes a surprise instead of a solved problem.
- Reviewing domains evenly instead of weight-proportionally, leaving the highest-weight domain (Infrastructure) under-rehearsed relative to its share of the exam.
Practice questions
Your diagnostic pass shows 65% on Infrastructure (30-35% of the exam) and 62% on Business Continuity (15-20% of the exam). With one week left before your final two timed runs, which domain should get priority review time first?
Business Continuity, because its raw score is lower
Neither — split time evenly across all four domains regardless of weight
Infrastructure, because it is both weak and carries the largest share of the exam
Whichever domain has the most flashcards remaining
At the 60-minute mark of a 120-minute, 60-question timed practice run, you have completed only 22 questions. What is the recommended response?
Stop the timer and restart the run from question 1
Continue at the same pace, since AZ-305 rewards untimed accuracy over speed
Switch immediately to review mode and stop answering new questions
Begin flagging harder questions and moving on more quickly to recover the pacing gap toward the 90-minute checkpoint
You are scoring 85% on the OpenExamPrep mixed-domain timed run but only 55% on Microsoft's official free practice assessment. What should you conclude?
You are not yet exam-ready and should keep practicing until both sources agree at or above roughly 80%
You are ready to schedule the real exam immediately
The official assessment must be miscalibrated and can be ignored
You should stop using the OpenExamPrep bank entirely and rely only on the official assessment
Key takeaways for your final study plan
- Run a domain-filtered diagnostic pass first, and prioritize domains that are both weak AND heavily weighted (Infrastructure, then Identity/Governance/Monitoring) over domains that are weak but lightly weighted.
- Follow a concrete day-by-day plan in your final two weeks rather than re-reading evenly across all 14 chapters.
- Use Microsoft's official free practice assessment as an independent calibration check alongside the OpenExamPrep timed mixed-domain runs — don't schedule the real exam until both agree at roughly 80% or higher.
- Practice with the same pacing checkpoints you will face on exam day: ~15 questions by 30 minutes, ~30 by 60 minutes, ~45 by 90 minutes, in a 120-minute, ~60-question run.
- Flag and move on rather than over-investing in any single question during timed practice — the habit you build in practice is the habit you will use on exam day.
