A study plan

Monday, April 26, two days before the exam, was the session Owen had expected to come first. "Most people make a study plan at the start and then ignore it," Priya said. "We made yours as we went, from your results. Today we write it down properly, for your last two days, and as a template for the next person." The next person already existed: Hélène Martin, an editor at Tidewater's partner publisher, planned to take GH-900 in the autumn, in English, which is not her first language. This lesson builds a study plan from three inputs: the exam weights, the candidate's own results, and the time available. It works through Owen's final two days and a six-week plan for Hélène.

The three inputs

A good plan answers one question: given the time I have, where will an hour of study raise my score the most? Three inputs answer it. The weights from lesson 1 say how much of the exam each area is worth. The results, from a self-assessment and practice questions, say how strong the candidate is in each area. The time says how many hours are really available, after work and life, and when. An hour spent on a heavily weighted area where you are weak is worth far more than an hour on a lightly weighted area you already know.

A simple scoring method

Priya's method gives each area a priority score: its weight times its gap, where the gap is how far the candidate's practice result falls short of the target of about 80 in 100. Areas at or above the target get a small maintenance score instead of zero, because knowledge fades. Hours are then shared in proportion to the scores. It is not precise, but it stops a candidate spending a day on a favorite topic.

The numbers confirmed what Owen felt: modern development deserved nearly half his remaining time. They also stopped him from doing what he wanted to do, which was another hour on collaboration, his favorite area, where he was already scoring full marks.

What to do in each hour

How a candidate studies matters as much as how long. Rereading notes feels productive but builds little. Three methods work much better. Retrieval practice: answering questions from memory, through flash cards, practice questions or explaining a topic aloud, as Owen did in the collaboration teach-back. Spaced review: returning to a topic after a gap, which strengthens memory more than one long session. Interleaving: mixing questions from different areas in one session, which trains the skill the exam needs most, recognizing which feature a question is about. Each hour in Owen's plan had a specific activity.

The plan ends early on Tuesday on purpose. Sleep consolidates what was learned during the day, and a tired candidate misreads questions, which lesson 10 showed was a large share of Owen's mistakes. Late-night cramming trades a small amount of new knowledge for a larger loss in reading accuracy.

A six-week plan for Hélène

Hélène's situation was different: six weeks, about four hours a week, and no earlier courses. Priya wrote her plan around the same three inputs, starting with the outline and the Microsoft Learn path rather than practice results, because there were none yet.

Because Hélène will take the exam in English, Priya added two items. She should request the 30 extra minutes available when an exam is not offered in the candidate's language, early, before booking. And she should do her practice questions in English from the start, so that the vocabulary of the exam, such as "triage", "ruleset" and "dev container", becomes familiar in the language she will read it in.

Fitting study around work

The hours in a plan have to exist in a real calendar. Owen blocked his study time as appointments, the same way he blocked editorial meetings, so that colleagues saw him as busy rather than free. Short sessions of 30 to 50 minutes with a break worked better for him than three-hour blocks, and placing review of a topic two or three days after first studying it gave him spaced review without extra hours. Priya's advice for Hélène was the same: four hours a week works best as four one-hour sessions on different days, not one long evening, because four separate returns to the material do more for memory than one sitting.

Practice assessments in the plan

Practice assessments serve two purposes, and the plan uses them for both. Early on, as a diagnostic, they show where the gaps are. Near the end, as a check, they show whether the plan worked. Between the two, they should not be repeated so often that the candidate remembers the questions, which inflates the score without improving knowledge. Owen took the official assessment twice, five working days apart, and used other mixed practice questions in between. A useful rule is that when a practice score rises, ask whether it rose because you remembered the question or because you could explain the answer.

Adjusting the plan as results arrive

A plan is a forecast, and forecasts should change when evidence arrives. Priya's rule for Hélène was to recalculate the priority scores after each practice assessment and move hours accordingly, but never more than once a week, so that one bad session does not throw the plan around. Owen's own plan changed twice: after the baseline assessment, which moved time from collaboration to modern development, and after the second, which showed that repositories had risen to 83 and no longer needed extra time.

If the result is a fail

A plan should also say what happens after a failing result, so the candidate does not have to decide while disappointed. Owen's note was short. Keep the score report, which shows performance by area. Wait at least a day before rebooking, which the retake policy requires anyway. Recalculate priority scores from the report, treating any area marked as weaker as having a large gap. Plan two to three weeks of study before the next attempt, because the policy requires 14 days between later attempts and because a quick retake without study usually produces a similar result. And remember that a fail says more about preparation than ability: the score report shows exactly where to aim, and a targeted plan is the best route to passing next time.

Logistics as part of the plan

A study plan includes the exam itself. Owen's plan had logistics items on fixed days: run the OnVUE system test a week before, check the booking confirmation and the name on his ID, confirm the room would be free and quiet, and click through the exam sandbox the day before. These take minutes, and each one removes a way to lose the exam before the first question.
