Under such life constraints, retake SPM is the only option - straight forward option. 

Face / ego = worthless in real life.

My honest 2 cents:

1. Please dissuade him from teaching course if he is not SERIOUS. We need quality, qualified and committed teachers.

2. If he is serious, take up a pre-U in field he is interested (ie: Sciences, Arts, Humanities, Commerce) > Undergraduate in same field > teaching diploma > teaching licence from MoE > Teacher

3. Chances are, he can still enter civil service with the above route.

4. Timeline: pre-U 1 year, Degree 3-4 years, Teaching Diploma 6 mths to 1 year

5. Cost: ballpark figure: fully loaded around MYR50k-100k depending on field of study in local private (has ruled up government univ as he is not qualified for even matric, pre-asasi or diploma if he is non)

Disclaimer: All this work if there's money and his willpower. Else refer to 1), please, for the love of himself and others, do something else.

No degree, no master, no phd.

There's no way you can skip degree to MBA.

I just checked. It seems that you will need at least a cgpa of 2.5 for degree or APEL 7 to enroll for the program.

Yes, very low. Besides, I wonder how did he enroll with a diploma?

No info provided for your field of study & work - then say your field need UK cert. What is your background, what was your diploma? How many years of working experience and why you need an MBA for your work?

University of Gloucest, macam x masuk akal the name.

Nama Pennsula College pun x masuk akal.

Went to the link you gave :-

Name of Qualification : Master of Business Administration in collaboration with University of Gloucestershire
Name of Institution : Peninsula College Shah Alam

Not surprised. Most would ask questions to justify their decision. It is hard to accept critical comments from others. I have seen quite a number of them. Ask a question >> gets a negative response with follow up questions >> MIA

something that have always puzzles me

i have asked a lot of students who don't excel academically but yet, they want to be teachers



what the heck?

what are they looking for in life?

if they don't like to read/study in the first place, how would they gain and impart knowledge to others?
