Akido,
WOW, this is a big decision for anyone to have to make, particularly while they are under such intense pressure from their own family, as well as their relatively poor financial situation, which is typical for a student of your age.
Effectively your question is related to whether you should apply for a job immediately after graduating in approximately three weeks from now, or whether instead you should delay doing this until after gaining certification as an industrial engineer, and by so doing improve both your qualifications and employability.
Either option is going to necessarily involve you taking certain risks. If you choose to apply for a job which you already have the qualifications and relevant work experience in over three weeks time, there are of course no guarantees that you would be successful. And this would only be a viable option if there are already suitable positions available in your local area for a person with your knowledge and skills.
The other option would be to study and sit for the industrial engineering exam in November, which would presumably make you better qualified for a job involving you taking on greater responsibility, presenting you with greater challenges more consistent with your high level of ability, and boost your weekly, fortnightly or monthly take home pay packet in the process.
Based only upon this reading I feel that you taking the extra risk of waiting until you you have gained your extra qualifications will be well worth it to you in the end. I feel that you would be short changing or cheating yourself out of the extra opportunities that having this certificate could offer you, and not just financially.
I also believe from what I am intuitively hearing when giving this reading that if you took a job immediately after graduation, that you would in hindsight regret not holding out for the better qualification, with the associated advantages that this higher level position could potentially give you.
There is nothing in your reading that even mildly suggests that you would not be successful if you sat for the industrial engineering certification exam in November, but if for some unforeseen reason you did not make the passing grade the experience of attempting it alone could be a valuable asset in your job hunting as well as give you a few new strings to your bow which could be useful to you in the future when negotiating your salary package with a prospective employer.
BTW if you did fail your November exam (unlikely according to your reading), how soon would it be before you could try again? At 21 years of age I feel that you have considerable elbow room in not having to simply take a job because you are too old to have a reasonable chance of being offered another suitable one in enough time.
Your relatively young age and the fact that you are not yet set in your ways of doing things and because you will pick up new skills more quickly than an older worker could in the long run be just as valuable to you as your industrial engineering certificate.
But with both of them (your age plus your certificate) working in your favour with companies which you would be looking at for your next job in the area of industrial engineering, these could be a formidable and highly competitive and lucrative combination, if you were only willing to wait the extra eight months to the exam.
There is only one condition being placed upon this. As most companies go into relative recess during the Christmas New Year period, and you would be doing your exam in November, you might need to be temporarily unemployed during the most expensive time of the year. When deciding whether or not to choose this option, determine whether you have enough money in reserve to tide you over between passing your exam and being able to look for a job in early 2012 when these companies reopen for business.
Another thing to consider is the aftermath or residue of the global financial crisis, which is still even now forcing companies to prune their workforce, instead of taking on new and inexperienced trainees with their new qualifications still hot in their hands. It is clear that your decision is much more complex than many people might realise that it is at this stage, but overall I would advise you that by taking a job immediately after your graduation in just under a months time, you would be seriously selling yourself short, and be unknowingly losing golden opportunities, which you may never have again when you are older.
But in the end it is entirely your decision to make as to which of the two option you will ultimately go with. There may be other factors at work here that I am unaware of but you are not, and therefore you are better qualified and placed than I am to make what could turn out to be a life and career changing decision.
After all, it is your working life and not mine which is on the line here.
Only use the information from this reading in combination with relevant information from other non intuitive sources. Use both logic and intuition (either your own inner guidance or someone else's as in a reading), to steer you in the best direction for you, and any dependants.
Wishing you every success and good luck. I have every confidence that you will do whatever you feel is necessary to maximise your chances of getting a better and more professionally satisfying job than you would have been looking at, immediately upon graduating.
Some risks ARE still worth taking, for the many potential benefits which they could offer you further down the line.
