A 170 out of 200 in NET-Engineering means 85% correct, so you can afford 30 wrong or guessed answers across roughly 100 Mathematics, 60 Physics and 40 English questions. With no negative marking, it also means reaching every question in 180 minutes: if you only properly attempt 180, you need about 92% of those right.
Key facts
- NET-Engineering: Mathematics 50%, Physics 30%, English 20%
- Derived question counts: 100 Mathematics, 60 Physics, 40 English
- 200 MCQs, 180 minutes, about 54 seconds a question
- No negative marking
- NET is 75% of the NUST aggregate

NUST publishes weightings, not question counts. The 100, 60 and 40 used below are derived by applying the weightings to the 200-question total. Treat every per-section number here as derived.
What 170 is worth in the aggregate
NET carries 75% of the aggregate. A 170 contributes:
170 / 200 * 75 = 63.75 aggregate points
each NET mark = 75 / 200 = 0.375 aggregate points
Add your school marks. A student with 990 of 1100 in matric and 473 of 550 in FSc part 1 would get:
SSC: 990 / 1100 * 10 = 9.00
HSSC: 473 / 550 * 15 = 12.90
NET: 170 / 200 * 75 = 63.75
Aggregate = 85.65
Whether that is enough depends on the programme and the year. NUST publishes the previous session's closing merit for guidance. Run your own numbers in the aggregate calculator, and see what NET score you need for how to read closing merit.
Three ways to split 170
Every question is worth one mark, whichever section it is in. So 170 can come from many splits. Three of them:
| Split | Mathematics (100) | Physics (60) | English (40) | Total |
|---|---|---|---|---|
| Even | 85 (85%) | 51 (85%) | 34 (85%) | 170 |
| Strong English | 82 (82%) | 50 (83%) | 38 (95%) | 170 |
| Strong Mathematics | 90 (90%) | 48 (80%) | 32 (80%) | 170 |
The second row is the one most students should aim for. Getting 38 of 40 in English is easier than getting 90 of 100 in Mathematics, because English questions are short and the gap between knowing a word and not knowing it is fast to close. Each English mark you add lets you lose one more Mathematics mark.
What none of the rows allows is a weak section. Drop to 60% in Physics (36 of 60) and you need 134 out of 140 elsewhere, which is 96% across Mathematics and English. That is not a plan.
You have to reach every question
170 has a second condition, and it is about speed. There is no negative marking, so anything you do not get to properly becomes a guess. A blind guess on four options is worth 0.25 marks on average.
If you properly attempt N questions and blind-guess the rest, the accuracy you need on the attempted ones is:
required accuracy = (170 - 0.25 * (200 - N)) / N
| Properly attempted | Blind guesses | Accuracy needed on attempted |
|---|---|---|
| 200 | 0 | 85% |
| 190 | 10 | 88% |
| 180 | 20 | 92% |
| 170 | 30 | 96% |
| 160 | 40 | 100% |
Every 10 questions you run out of time on raise the accuracy bar by 3 to 4 points. At 160 attempted you would need a perfect score on all of them. So a 170 is as much about speed as about knowledge.
Guesses where you can rule out two options are worth 0.5 marks each, which helps. But you cannot plan on that for questions you never read.
The pace that 170 needs
180 minutes over 200 questions is 54 seconds a question. That average hides how uneven the sections are. Using the budget from the CBNET pacing post:
| Section | Derived questions | Budget | Seconds per question |
|---|---|---|---|
| Mathematics | 100 | 95 min | 57 |
| Physics | 60 | 50 min | 50 |
| English | 40 | 20 min | 30 |
| Buffer | 15 min |
For a 170, you need to stay inside those budgets while keeping accuracy around 85%. In practice that means:
- English in 20 minutes or less. If English takes you 35 minutes, you have taken 15 minutes from Mathematics, which is about 16 questions at 57 seconds each.
- No Mathematics question longer than about two minutes on the first pass. Pick your best answer, save, flag, move on. Two minutes on one question costs you about one other question.
- Physics at 50 seconds. Many NET Physics MCQs need one formula and one substitution. If you are deriving, you are too slow.
Checking whether you are on track
A single mock score of 170 is not proof, and a single 140 is not failure. Different papers have different difficulty. Track the average of your last three full-length papers, and track two numbers for each one:
- Accuracy on attempted questions. Below 85% means content gaps. Fix chapters.
- Questions properly attempted. Below 190 means pace. Fix speed with timed sets.
Many students fall short on both. Fix the bigger gap first. If you attempt 175 at 90%, speed is your problem: reaching 195 at the same accuracy gives you about 177. If you attempt 198 at 78%, it is content.
FAQ
Is 170 a good score in NET?
170 out of 200 is 85%, which adds 63.75 points to your aggregate. Whether it is enough depends on your programme and your school marks, so compare your full aggregate with the closing merit NUST publishes.
How many questions can I get wrong for 170 in NET?
30 out of 200, counting wrong answers and unanswered questions together. On the derived counts, an even split is 15 in Mathematics, 9 in Physics and 6 in English.
How much aggregate does 170 in NET give?
170 divided by 200, times 75, is 63.75 aggregate points. Your matric adds up to 10 and your FSc up to 15.
How fast do I need to be to score 170 in NET?
Fast enough to properly attempt at least 190 questions in 180 minutes. That means about 57 seconds per Mathematics question, 50 per Physics question and 30 per English question.
