Frequently Asked Questions

Can I use ECAT score for NUST?

No, NUST only accepts its own NET test. Similarly, UET Lahore does not accept NET or NAT scores. Each institution has its own required test.

Which test is the hardest?

NET is generally considered the most difficult due to its length (200 questions), negative marking, and the high competition for NUST seats. ECAT is moderate in difficulty, and NAT is considered the most accessible of the three.

Can I take all three tests in the same year?

Yes, and many students do. Since the tests are conducted at different times, you can prepare for and attempt all three. Just make sure to check the dates and plan your preparation schedule.

Do entry test scores expire?

Yes, all three test scores are valid only for the admission cycle in which they are taken. You cannot use last year's ECAT, NET, or NAT score for this year's admissions.
