Không dễ và không khó
Is the extra syllable after "Học" just like saying "um"?
No it's a side effect of the way you pronounce words ending in -oc/ôc/uc which require you to bind your lips together creating a pseudo -m sound at the end.
No it should not sound like that. This voice talent (recorder) has this habit (making the first word unnecessarily long).
