MDCAT, ECAT & NUST NET Mark Impact Simulator
See how every mark changes your aggregate. Pick your exam, enter your Matric and FSc marks, then find out what you would score, or what you need to reach your target.
Choose your exam
Type the aggregate you are aiming for. Check closing merit on the official university notices yourself, since it changes every year.
What 10 extra marks are worth
The same 10 marks move your aggregate by very different amounts depending on where you earn them.

How the mark impact simulator works
The simulator shows how your aggregate changes when your marks change. It covers three admission routes: the MDCAT for medical colleges, the ECAT for UET engineering programs, and the NUST Entry Test (NET). Choose your exam at the top, enter your Matric and FSc marks, and the rest updates as you type.
The three formulas
All three aggregates combine Matric, FSc and a test score, but the weights are very different:
| Exam | Matric | FSc | Test | Test total |
|---|---|---|---|---|
| MDCAT | 10% | 40% | 50% | 180 |
| ECAT | 17% | 50% | 33% | 400 |
| NUST NET | 10% | 15% | 75% | 200 |
The simulator uses the same formulas as our MDCAT, ECAT and NUST calculators, so the numbers always agree. Universities can update their rules between admission cycles, so confirm your program's formula in its official admission notice before relying on any result.
What one mark is worth in each exam
Weight divided by total marks gives the points one mark adds to your aggregate. With Matric and FSc both out of 1,100:
| Exam | Test mark | FSc mark | Matric mark | Test vs FSc |
|---|---|---|---|---|
| MDCAT | 0.278 | 0.036 | 0.009 | 7.6x |
| ECAT | 0.083 | 0.045 | 0.015 | 1.8x |
| NUST NET | 0.375 | 0.014 | 0.009 | 27.5x |
ECAT: test and FSc marks are closer in value, so a strong FSc still matters a lot.
NUST NET: the test carries 75%, so one NET mark is worth about 27 FSc marks.
This is why the same student can see a big swing in one exam and a small one in another. The test is the most powerful lever in all three, but how powerful depends on the exam.
Worked examples
The same student, with 900/1100 in Matric and 950/1100 in FSc, in each exam:
MDCATScore 140/180
| Part | Marks | Points |
|---|---|---|
| Matric (10%) | 900 / 1100 | 8.18 |
| FSc (40%) | 950 / 1100 | 34.55 |
| MDCAT (50%) | 140 / 180 | 38.89 |
| Aggregate | 81.62% |
Scoring 155 instead of 140 lifts the aggregate to 85.78%.
ECATScore 300/400
| Part | Marks | Points |
|---|---|---|
| Matric (17%) | 900 / 1100 | 13.91 |
| FSc (50%) | 950 / 1100 | 43.18 |
| ECAT (33%) | 300 / 400 | 24.75 |
| Aggregate | 81.84% |
Scoring 340 instead of 300 lifts the aggregate to 85.14%.
NUST NETScore 140/200
| Part | Marks | Points |
|---|---|---|
| Matric (10%) | 900 / 1100 | 8.18 |
| FSc (15%) | 950 / 1100 | 12.95 |
| NET (75%) | 140 / 200 | 52.50 |
| Aggregate | 73.64% |
Scoring 160 instead of 140 lifts the aggregate to 81.14%. Twenty extra NET marks added 7.5 points, more than the whole of this student's Matric contribution.
How to use the results
Matric and FSc marks are fixed once your results are issued, so the entry test is the one number you can still change. Use "What do I need?" to set a realistic target for your exam, then compare that target with the closing merit of the programs you want. This page does not publish closing merit, because those figures change every year and differ by program. Check them on the official university notices.

Frequently asked questions
What is the mark impact simulator?
It is a tool that shows how your aggregate changes when your marks change. Pick MDCAT, ECAT or NUST NET, enter your Matric and FSc marks, then move the test-score slider or enter a target aggregate to see the test score you need.
Which formulas does the simulator use?
MDCAT uses 10% Matric, 40% FSc and 50% MDCAT (out of 180). ECAT uses 17% Matric, 50% FSc and 33% ECAT (out of 400). NUST NET uses 10% Matric, 15% FSc and 75% NET (out of 200). These match our MDCAT, ECAT and NUST calculators.
How many marks do I need to reach my target aggregate?
Choose your exam, enter your Matric and FSc marks, open the "What do I need?" tab and type your target aggregate. The simulator shows the lowest test score that reaches it. If the target is out of reach even with a perfect test score, it tells you the highest aggregate your Matric and FSc marks allow.
Why does one test mark change my aggregate so much?
Each mark is worth the exam's weight divided by its total marks. In MDCAT one test mark adds about 0.278 points, in ECAT about 0.083, and in NUST NET about 0.375. A single FSc mark adds only about 0.036, 0.045 and 0.014 points in those exams, when FSc is out of 1,100.
In which exam does the entry test matter most?
NUST NET, because the test carries 75% of the aggregate and one NET mark is worth about 27 FSc marks. In MDCAT the test carries 50%, and one MDCAT mark is worth about 7.6 FSc marks. In ECAT the test carries 33%, so FSc has the largest weight at 50%.
Can I improve my Matric or FSc marks to raise my aggregate?
No. Matric and FSc marks are fixed once your results are issued, so the entry test is the only part of the formula you can still change. Rules about retaking a test are set by the official admission authorities, so check their notices.
Does the simulator show closing merit from previous years?
No. Closing merit changes every year and differs by program and seat type, so this tool does not publish it. Enter your own target aggregate and compare it with the official merit lists and university notices.
What if my total marks are not 1,100?
Change the total next to Matric or FSc. The simulator recalculates every result, bar and scenario using the totals you enter.
Is this an official calculator?
No. It is an unofficial tool built on the published aggregate formulas. Your final merit position is decided only by the official merit lists, so confirm each program's formula in its official admission notice.
