From where should i practice mathematics MCQ's ??

Lol sorry mate. I havn't started preparing for entry tests yet because i'm busy with practical exams. I'll let you know if i find a good source

Ah it's really hard to explain maths like this. Anyway i'll try again.
Do you know how to expand a 3x3 determinant? This is the same thing. When you expand a 3x3 determinant, you are actually converting it into a lesser order matrix ,i.e a 2x2 matrix which is then solved by 'ad-bc' formula.
Now the given determinant was of 5x5 order. You expand it/convert it into a lower order determinant, i.e 4x4
You have got more than 1 4x4 determinants corresponding to the number of elements in that row or column. Now the technique was that if we use such a row or column for expansion which has only one non-zero entry, we get only 1 4x4 determinant. Had we considered a row or a column having more than 1 non zero entries, there would have been more than 1 4x4 determinants, which would have made the problem confusing.
Now using that 1 4x4 determinant, we again consider a row or a column for expansion which would give only one lesser order i.e, 3x3 determinant.
Then we expand the 3x3 determinant and solve it by ad-bc. I hope that helped

Ah, ok. Got it thanks

Haven't started preparing for entry tests yet, that's why I was asking! So, before that, from where are you doing questions then?

Alright. Btw will/have you read (some)topics from FSc books? Also, do you think if there's any need to do Maths questions from first year's book?

Just to confirm: This thread can be used to discuss entry tests for NUST and GIKI, right? Btw ECAT is only to apply for UET, right?
