I'm a bar school student. Well in terms of law degree quality obviously UKM is quite on the lower side compared to other unis, but it'll do. At least you'll be able to skip CLP and straight go for chambering.

It's not even a dilemma, whether business admin or law. Obviously, the choice is law. Likelihood of you going far with a business admin degree is slim.

If I were you, UOL law degree and CLP is the way to go. I second @KuzumTaiga suggestion for UOL + CLP

choosing LLB over business admin just doesn't "seem" to be a better choice, it is a no-brainer one.

Well... my statement is going to step on a few toes here, although most in the field would agree with me. UKM's LLB reputation is on the lower rung of the ladder when compared against UIA, UM, UUM, UOL, Cardiff, MMU and I daresay UiTM, list goes on.
In my years I've had more than several encounters with UKM law students and graduates... save for a couple, the rest are rather... on the slower side? Some could not even converse in proper English (similar to this instance although it is an extreme example https://www.youtube.com/watch?v=0ffbSgUy_1E).

Perhaps their graduates would come to eventually serve in Shariah, judiciary (eg. I've met two magistrates who were from UKM) When I had asked our UKM counterparts during some legal event in 2014, they told me that their course is considered fully in BM except for certain papers (double check before enrolling if it concerns you). It shouldn't affect their employability in govt positions especially when everything is in Bahasa Malaysia, however in the upper courts we use English, and you'd be torn to shreds during cross examinations. I am not basing my conclusions on only a couple of encounters I've met with people from UKM, this is from on my detailed conversations with about a baker's dozen of them.

Pop into any major law firm's associates' and partners' rosters, i.e. Shearn, Shook Lin, Thomas Philip, Cheang & Ariff, Raja, Darryl & Loh blah3 you'll notice that there is an absence of UKM graduates. (Here's an example: http://shooklin.com.my/lawyers/associates/) That industry of upper-tier legal eagles is not skewed against local U grads favoring British LLB holders, for there are many UIA, UM, UUM graduates in them.

In conclusion, there is no denying that if you are motivated to go far in your career, it wouldn't hurt to consider UOL. There is PTPTN, it is arguably a much harder course in combination with the CLP requirement, but it will place you ahead of the pack, if you steeled through it.

Ultimately, a graduate's attitude and how he/she presents himself during interview is also an important factor. Just try to remember that this field, like any other, is an unjust one. There will be prejudices, there will be a lot of judging and looking down on, just do your best and recall that statistics do not lie.
