If you've always wanted to be an aircraft engineer then stick with it.
What can you do to make the letter and CV you send to an MRO asking for work experience stand out more than the other 25 that might land on the manager's desk to make him/her give you a go?
When do you need to start your work experience - have you completed your modules or just starting out at the training organisation?
Are there any training organisations nearby where you can do handskills training?
Are there any flying clubs near where your studying where you could "volunteer" to help out in your spare time?
I'm not giving you answers to any of the above, it's up to you how you will break into the industry. Your instructors should be helping you though and not just taking your money.
As before, good luck. It won't be easy but if you want it enough you will find a way.
