Dear experts,

I am working adults and currently pursuing part time bachelors of technology in electronics in one of the open university here. At age >30, I have to choose wisely which elective subjects are most useful and demanding to determine my next path of my career soon after I graduated. I am still cannot my make decision to choose 2 electives subjects as my major:

discovering physics and chemistry
problem solving with object in Java
operating systems
field theory
quality and reliability
information theory
electronics materials and devices
microelectronics (VLSI Systems)

I am currently working in hi-tech semiconductor industry and hopefully after graduation soon I can get or change career to other technical field especially in oil & gas (Hopefully it is not too late for me consider my age at that time ). So I hope someone here can help me to choose wisely.
Thank you.

Hi exquisite_markas,

Thanks for the advice. Yes you are right... electronics and oil & gas are two different field but I have no choice at my current university as they offer only bachelor in electronics for engineering fields. So this is the only choice that I can pursue my degree related to my working experience. Even though it focus more on electronic field of study but I hope it has some subjects that I can relate to any requirement for any electrical/electronic jobs in oil & gas field and I believe the scope of oil & gas field is wide.

Btw, thanks again for your advice.
