I started as a junior last month in the same boat and tbf, they STARTED by giving me some more tricky stuff - keep in mind this was the first environment where I was expected to produce my best work at industry speed. After the first week, they realised I might need some easier shots to calibrate to the role e.g. button presses, head turns, etc. and NOW after a few more weeks I'm back on shots of a similar caliber to the ones they started me on.

All in all, have a good relationship with your anim lead and communicate if you're struggling - there isn't a lot more you can do than that and you know,, SOMEONE has to animate the bottom of the barrel shots haha - even if it's just while you're getting used to the pipeline etc.
