Hey
tommowg,
I finished full time education 8 years prior to starting my ATPLs and I didn't find the material too difficult, broken record time but it is very much the quantity of information you need to absorb here rather than overly difficult concepts.
The thing I found hardest was to get back into the intense study mindset, and as you will find having just finished a degree it shouldn't be too tough for you. My coursemates who had just finished Uni seemed to be able to hit the ground running but it took a valuable 3 weeks or so for my cogs to get up to speed (especially as we started with POF!)
If you're used to studying from 8am to 9pm on weekdays and at least 4 hours per day at a weekend then you should be grand, that was my regime and I managed mid 90's % average. Hope that helps!
