Thanks, but still not resolved.
I entered tuition and number of months of full-time studies: 3. Still UFILE automatically claims CWB (I think because it is only 3 months, if I enter 4 as a try, it does eliminate the CWB). But, anyways, he was living abroad those 3 months, (so not a resident of Canada throughout the year), so shouldn't qualify!!
If we claim CWB without rightfully qualifying, we will get in trouble with CRA. We simply would very much prefer not to claim it at all!
Thanks,
