It's good that you bothered to start a topic on this, it shows
that you care, at least. A little worry helps, just not too much.
There's hope yet.
If you cannot concentrate on studying, try doing it in a group. Get
people who actually study though, else it'll end up just being
another fun outing.
Otherwise, like someone said earlier, do TYS / exercises. Reading
is more boring than doing! And when you get stuck at an exercise,
refer to notes and learn.
I'm sure you can do it, even if I failed to. Haha. -scuff-
