Take 6 to 8 full-length mocks before NET, spread over the last six weeks, and never more than two in one week. Each mock costs about six hours once you count the review, so more than eight leaves too little time to fix what the mocks find.
That number assumes you have already covered most of the syllabus. Before that point, timed chapter sets teach you more than full papers do. The schedule and the reasoning are below.
Key facts
- NET is 200 MCQs in 180 minutes, about 54 seconds a question
- No negative marking, so every mock should be answered in full
- NUST's portal has one free Sample Test. NUST publishes no past papers
- SailToNUST has 6 full-length NET-Engineering papers at /flp, free
- NET-2027 Series-1 CBNET starts 17 November 2026 in Islamabad (tentative)

Why 6 to 8, and not 20
A mock has two halves. The three hours of sitting tell you your score. The review tells you why, and only the review changes your next score.
Here is what one honest review takes. Out of 200 questions, a student scoring 130 has 70 wrong or guessed. Spend two to three minutes on each one: rework it, read the explanation, and note the chapter. That is two to three and a half hours. Add the three-hour paper and a mock is a six-hour day.
sitting 180 min
review, 70 items 140 to 210 min
total about 5.5 to 6.5 hours
Then you need days to act on it. If a mock shows you lost eight marks in conic sections, you need two or three study sessions on conic sections before another full paper can show whether the fix worked. Two mocks back to back measure the same weaknesses twice.
So the limit is review time and repair time, not stamina. Over six weeks, 6 to 8 mocks leaves four or five study days between papers. Twenty mocks in the same window would leave none.
When to start
Start full mocks when you have studied roughly three quarters of the syllabus. Before that, a full paper mostly tells you which chapters you haven't done yet, which you already know.
Until then, use timed sets. Pick 20 questions from one chapter, give yourself 18 minutes (54 seconds each), and mark them. The practice pages are split by chapter for this.
If you are three weeks out and haven't started, the minimum is three full mocks: one now, one in ten days, one five days before the test.
A six-week schedule
This plan gives you 8 mocks. Week 6 is the furthest from your test.
| Week before NET | Mocks | What the mock is for |
|---|---|---|
| 6 | 1 | Baseline. Find your three weakest chapters |
| 5 | 1 | Check the first repairs. Start timing each section |
| 4 | 1 | First full run on the CBNET interface |
| 3 | 2 | Pacing. Hit your section time budgets |
| 2 | 2 | Same conditions as the real test: morning or afternoon slot, no phone, no breaks |
| 1 | 1 | Five days before the test. Confidence, not new learning |
In the two-mock weeks, leave at least two clear days between papers, for example Monday and Thursday. Put the last mock four to five days before your test date, not the day before. The last week is for light revision and sleep; the last week before NET covers that.
If you only have time for 6, drop one mock from week 3 and one from week 2.
Where the 8 papers come from
NET-Engineering candidates can do this for free:
- 6 papers from the full-length papers page. Each is 200 questions at NUST's current weightings and opens in the CBNET interface.
- 1 run of NUST's own Sample Test on the admissions portal, to see the official interface once.
- 1 more paper from another free source, such as Nustrive's FLP app (20 NET-Engineering papers, no login), or a repeat of your weakest FLP after a two-week gap.
The other NET papers (Business, Applied Sciences, Architecture, Natural Sciences) have no SailToNUST full-length paper yet. Nustify and Parhlai each have a free 200-question FLP for Business and for Applied Sciences. Past those, build your own 200-question mock from chapter practice in the right proportions. Whether those are worth paying for is covered in do you need paid NET mock tests.
How to review a mock in one sitting
Do the review the same day or the next morning, while you remember why you picked each answer. Sort every lost mark into one of four bins:
- Didn't know it. Goes on the chapter list for the coming week.
- Knew it, ran out of time. A pacing problem. Check where your clock went against the section budgets in the CBNET pacing guide.
- Careless. Misread the question, wrong sign, wrong option clicked.
- Interface. Forgot to press SAVE, or lost time paging back with Prev.
The counts matter more than the score. If bin 1 shrinks from mock to mock, your study is working. If bin 2 stays large, more content won't help; you need faster methods. Bin 4 should be zero by week 3. If it isn't, do a run on the CBNET simulator and nothing else that day.
Signs you are taking too many
- Your last three scores sit within 5 marks of each other, and the same chapters keep failing.
- You skip reviews to fit in the next paper.
- You feel you "know" the papers because questions start to repeat.
Any one of these means stop sitting papers for a week. Spend that week on the chapters from bin 1, then sit one more.
What about the real NET as a mock?
NUST uses your best score across the cycle's series, so an early series attempt works as a mock under real conditions. It costs Rs 5,000 per attempt, against nothing for a home paper. Deciding which series to sit is its own question, covered in which NET series to take.
FAQ
How many mock tests are enough for NET?
Six to eight full-length mocks over the last six weeks, with each one reviewed before the next. Fewer than three is too few to check whether your fixes are working.
Can I take two NET mocks in one day?
You can, but you shouldn't. A mock is only useful once you've reviewed it, and the review of one paper takes two to three hours. Leave at least two days between papers.
When should I start full-length NET mocks?
Once you have studied about three quarters of the syllabus. Before that, timed 20-question chapter sets are a better use of three hours.
Should I do a mock the day before NET?
No. Sit the last one four to five days before your test, review it, and keep the final days for light revision and rest.
Are there free full-length NET mocks?
Yes. For NET-Engineering, Nustrive's free FLP app has 20, SailToNUST has 6 at /flp, and Nustify, Parhlai and Tayarri have one each. NUST's admissions portal has one official Sample Test.
