hey Footyfan,
I am wondering like you are. I don;t have any technical background either. Since my higher secondary all I took was management major till my my master. But Struggling a lot to find a decent job yet. Now all I know is NO Pain NO Gain...
I am going with online training for QA too and very optimistic that it will work. I am planning on giving my best. I know it might take a year or more but once you get there just need to hang on for 1 year  after that u made your career....
so don;t be afraid.....

and ofcourse they won;t give their best training and knowledge ..and the training they provide will be on surface ..its you who have to do the deep study...

Regards,
Kripaya
