STMKG

Expect multiple-choice items across the eight subject areas, sat in one sitting. Each item has a single best answer, and there is no essay component. Because the number of items, the time allowed, and the scoring rules are set by the organising body for each intake, check the current official announcement from STMKG or BMKG before you plan your pacing.

It is competitive rather than conceptually exotic. The mathematics and physics items are at senior-secondary level but are designed to separate candidates, so speed and accuracy on multi-step numerical work matter more than obscure theory. Most candidates find the difficulty comes from the clock and from careless errors, not from topics outside the national curriculum.

Retake rules depend on the intake and on your eligibility as a graduate, so they are not something to assume. The official STMKG and BMKG announcements state whether a new selection cycle is open and who may register. Treat each cycle as a fresh application with its own requirements, and confirm your status with the official body rather than relying on hearsay.

Follow the weights: mathematics and physics together carry nearly half the marks, so give them the largest share. Chemistry and biology need solid conceptual coverage, while Indonesian and English reward steady reading practice. Keep aptitude and disaster/MKKG awareness as short, regular sessions rather than a final cram, and review errors weekly.

Running out of time on calculation-heavy items, misreading a question's final line, and neglecting the lower-weight sections until too late. Another frequent problem is practising only familiar question types, which builds false confidence. Simulate full papers under timing, log every mistake by cause, and revisit weak topics until you can solve them without prompts.

There is no official figure, and it depends on your starting level. A practical approach is several months of consistent work: a diagnostic mock, six to ten weeks rebuilding fundamentals, then timed mixed practice with weekly review. Candidates who start late usually sacrifice the physics and mathematics depth that the weighting rewards, so begin with those.

Yes, but understanding beats recall. You should know core formulas cold and also know when each applies, because items often disguise a standard problem. Build a one-page formula sheet per topic, then practise deriving and using each entry in problems so that recognition is fast under exam pressure.

Only the official STMKG and BMKG channels publish current registration windows, eligibility rules, document requirements, and any fee or scoring details. This page does not state them because they change between intakes. Check those sites directly, note the deadlines early, and prepare your documents before the window opens.

It carries a small weight, so it should not displace mathematics or physics, but it is easy marks for candidates who read regularly. Focus on how BMKG monitors earthquakes, tsunamis, and severe weather, plus basic hazard terminology. Short, consistent reading beats a last-minute sweep of unfamiliar material.
