My advice is pursue for more general degress like Mechanical or Electrical engineering first if you are really uncertain to go into aerospace industry to leave a backdoor for yourself in the case that you are not interested anymore. If you are certain to go for aerospace industry then go ahead pursue the Aerospace degree. Even with Aerospace/Mechanical/Electrical degrees when you have joined the aerospace industry eg. licensing or MRO, you will still need to go for further specialization, training or take licensing papers like CAAS.

For myself i joined the aerospace industry after poly after getting a mechanical eng diploma as my parents are retired and unable to fund for my degree studies. Lucky enough i am able to take time off from my work to study part time for my degree.
