Supplementary vs Repeat WAM Calculator

Failed a unit? Compare how a Monash supplementary pass (capped at 50%) stacks up against retaking the unit — both affect your WAM differently.

Verify current WAM with the Monash WAM calculator. Read recovery context in our failed unit WAM guide guide.

Your Transcript Snapshot

Enter your current WAM with the fail included, plus the failed unit details from WES.

How Monash Treats Each Path

Supplementary: eligible fails (often 45–49% with NS) get one last chance. Pass → unit becomes 50% (P). Fail → original mark stays.

Repeat: you enrol again and can earn any mark, but Monash WAM counts both the failed attempt and the repeat in the credit-weighted average.

Example: WAM 68.25 on 24 cp with a 48% fail in 6 cp → supplementary pass lifts WAM to about 68.75. A repeat at 75% gives about 69.60 because both attempts count.

What This Calculator Does

Compares WAM after supplementary pass at 50% versus repeating the failed unit at a mark you choose. Shows breakeven repeat mark where repeat beats supp, accounting for both attempts counting in repeat scenario.

Supp replaces fail mark without adding cp. Repeat adds second attempt cp with both marks typically in WAM.

How the Calculation Works

Supp scenario: swap fail mark for 50 on same total cp. Repeat scenario: add repeat cp with new mark while fail remains — total cp increases, WAM recalculated over larger denominator.

Breakeven repeat mark is where repeat WAM equals supp WAM — score above it to prefer repeat on maths alone.

When Students Should Use This Calculator

After failing a unit when both supp exam and repeat are realistic options. Especially for 12 cp cores where mark differences swing WAM materially.

  • Failed LAW2101 (12 cp) with supp offered.
  • Deciding if repeating MAT1830 for 75+ beats capped 50.
  • Quantifying WAM cost of carrying two attempts.

Step-by-Step Guide

Follow this workflow each time you use the tool so your inputs match WES or your unit guide.

  1. Enter current WAM with fail included.
  2. Enter total cp and failed unit cp.
  3. Enter fail mark.
  4. Enter expected repeat mark (if considering repeat).
  5. Compare supp WAM vs repeat WAM.
  6. Read breakeven mark and consult faculty advice.

Practical Examples

Worked scenarios below use realistic Monash-style marks and credit loads. Enter the same values in the calculator to verify.

6 cp fail — supp often wins

WAM 70, 120 cp total, 6 cp fail at 42. Supp 50 → WAM 70.4. Repeat at 65 with both attempts → WAM 69.8 (worse due to double counting). Breakeven repeat ≈ 72+.

12 cp fail — repeat at 80 beats supp

WAM 68, 108 cp, 12 cp fail at 38. Supp: WAM 69.2. Repeat at 80: WAM 71.5. High repeat mark justifies repeat path.

PathWAM
Supp 5069.2
Repeat 8071.5

Breakeven near distinction

WAM 69.5, repeat breakeven ~74. Below 74, take supp; above 74, repeat wins on WAM.

Low repeat expectation

Expected repeat mark 55 — supp at 50 nearly identical WAM; supp saves time and double-count risk.

Honours-bound student

WAM 76, 12 cp fail at 45. Supp → 76.5. Repeat at 85 → 78.2. Pursuing repeat if confident in distinction repeat performance.

Common Mistakes Students Make

  • Assuming repeat removes fail from WAM — both often count.
  • Ignoring supp cap at 50 when comparing to repeat 65.
  • Choosing repeat during exchange semester without timetable check.
  • Using WAM excluding the fail as baseline.

Tips to Improve Academic Performance

  • Take supp when breakeven repeat mark exceeds your realistic expectation.
  • Use failed unit calculator first for scenario overview.
  • Confirm repeat policy with faculty — some courses limit attempts.

Important Notes About Monash University Policies

Supplementary assessment availability follows unit and faculty rules. Repeat enrolment adds credit points and may affect progression timelines.

Supplementary vs Repeat at Monash

When you fail a unit, Monash may offer a supplementary assessment. Passing at 50% replaces the fail mark in WAM for that unit without adding extra credit points. Repeating the unit adds a second attempt — and under normal rules both the fail and repeat marks can count toward WAM, increasing total credit points.

This calculator compares WAM after a supplementary pass at 50 versus WAM after a repeat attempt at a mark you choose. It also estimates the repeat mark needed to beat the supplementary outcome.

Which Path Is Better?

A supplementary pass is often better for WAM when you only need 50 and want to avoid carrying two attempts. A repeat can beat supp if you can score well above the breakeven mark — especially on high-credit units where a distinction repeat outweighs a capped 50.

Timetable, progression rules, and faculty advice matter as much as maths. You cannot repeat during an exchange semester if it clashes with approved travel, for example.

  • Enter current WAM with the fail already included.
  • Check supp eligibility on official Monash channels.
  • Read our supplementary exam WAM guide and repeat unit guide.

Frequently Asked Questions

What mark do you get if you pass a Monash supplementary?

If you pass a supplementary assessment, your final unit result is capped at 50% (P). You cannot score higher through supplementary.

Does a failed supplementary change WAM?

If you fail or do not complete the supplementary, your original fail mark (N or NH) usually remains and WAM stays as-is for that unit.

How does repeating a unit affect Monash WAM?

Monash includes both failed and repeated unit attempts in WAM. A repeat adds another weighted entry — it does not automatically remove the first fail from your average.

Is repeat or supplementary better for WAM?

It depends on your fail mark, unit credit points, and what you could realistically score on a repeat. Use this calculator to compare supplementary pass (50%) against your planned repeat mark.

Where do I get my current WAM and credit points?

Check WES or your academic transcript for cumulative WAM, unit marks, and credit points. Include the failed unit when entering current WAM.

Is this official Monash advice?

No. This is an independent planning calculator. Always confirm supplementary eligibility, repeat enrolment rules, and official WAM with Monash student services.
