I wanted to know if I could transfer from Le Cordon Bleu to J&W, and if I can will I loose my credits?
You need to talk to admissions and have your transcripts transferred for review. An ugly truth is that many schools are real bastages about accepting credits from other schools. Another thing I would suggest depending on how far along you are in the program is to contact a Chef instructor at J&W, explain your situation and see if they will allow you to test and start in a cycle.
Best of luck,
