Which Wave Is Actually Open to Bimo: A Constraint-Timeline Problem
Bimo is applying to IUP UGM and has downloaded the selection calendar. Wave 1: registration 6 January–7 February, documents verified by 12 February, written test 22 February, interview 1–5 March, results 14 March. Wave 2: registration 3 March–4 April, documents by 9 April, written test 19 April, interview 28 April–2 May, results 12 May. Wave 3: registration 5 May–6 June, documents by 11 June, written test 21 June, interview 30 June–4 July, results 18 July. Seats are filled wave by wave, and a program may close a wave early if capacity is reached.
Bimo's constraints: his school releases rapor semester 5 on 20 January; his IELTS is booked for 22 March with results on 4 April; his ijazah and legalised transcript will only be issued after graduation in late June; he has a family obligation from 27 April to 3 May; and his parents will pay the application fee once only, with no refund if he withdraws. He has not yet checked whether the program accepts a headmaster's statement in place of a pending ijazah.
1. Determine which wave Bimo can realistically target, treating each deadline as a constraint rather than a suggestion.

Work through each wave against the binding constraint, which is the latest-arriving required document.
Wave 1 (documents by 12 February): his IELTS result exists only on 4 April. Unless a conditional English submission is allowed - which the calendar does not state - Wave 1 is closed to him. Do not assume away a hard deadline.
Wave 2 (documents by 9 April): the IELTS result lands 4 April, five days before the document deadline, and the rapor from 20 January is available. The ijazah, however, arrives in late June, well after 9 April. So Wave 2 works only if a headmaster's statement or conditional offer is accepted for pending graduation documents.
Wave 3 (documents by 11 June): the ijazah still arrives after the deadline, so Wave 3 poses exactly the same conditional-document question. This is the key insight - the ijazah is not what separates the waves; the English result and the interview clash are.
The real constraint on Wave 2 is the interview window, 28 April–2 May, which overlaps his family obligation of 27 April–3 May.
2. Given that seats are filled wave by wave, assess the cost of waiting and propose a decision rule for Bimo.

Waiting is not free. Three costs compound. First, capacity: if his target program reaches its intake in Wave 1 or Wave 2, Wave 3 has no seat to offer regardless of how strong his file is. Second, fee irreversibility: with one non-refundable payment, a Wave 2 attempt that fails on documents consumes the only shot. Third, score validity and momentum: a late application leaves no time to retake the IELTS or repair a document defect.
Decision rule: apply Wave 2 if and only if two conditions are confirmed in writing before payment - (a) the program accepts a headmaster's statement or conditional offer pending the ijazah, and (b) an interview slot outside 27 April–3 May can be requested and is granted when the conflict is declared at registration. Ask the admissions office in writing (email, not phone) so there is a record. If either condition fails, apply Wave 3, but first ask the program to confirm remaining seat capacity in writing, and pay as early in the Wave 3 window as possible rather than on the closing day.
If both conditions hold, Wave 2 dominates: it clears the English constraint and preserves Wave 3 as a fallback only if the fee were refundable, which it is not.
3. What single unknown most changes your recommendation, and what secondary fact would you also check?
Read the worked answer
The single decisive unknown is whether the program accepts pending graduation documents - a headmaster's statement or a conditional offer in place of the ijazah. That one rule determines whether Waves 1, 2 and 3 are all governed by the same constraint or whether the early waves are genuinely open. Everything else in Bimo's file is schedulable: the rapor is early, the IELTS result is knowable, and the family conflict is a request for a different slot.
The secondary fact worth checking is the program's closure history: whether it filled its intake in Wave 1 or Wave 2 in the previous cycle. If it closed early last year, the cost of waiting jumps and the case for pressing for Wave 2 with a conditional document becomes much stronger. A third, lower-priority check is whether the English certificate must be submitted at registration or may be supplied before the written test - that would move the Wave 1 verdict from impossible to arguable.
