Haribol
Is the course you are doing going to get you a good well payed job, is a well payed job you need to pay off your course fees if so carry on with it.
When you have thought about the above then pray to Lord Krsna about how you can mix a job and spritual life, one way of doing this is to realise that what you are doing is for the glory of krsna and that you may be able to use your new found skills in the service of Krsna and Devotte's. Think about this in a SPRITUAL WAY not a KARMI WAY.
Hopes this helps
Hare Krsna
