Io posso is used "as it is", as in...
Io posso nuotare. I can swim.
(Io) ti posso aiutare? Can I help you?
The subjunctive conjugation, io possa, is used in front of "che":
Che io possa... That I can...
Pensi che io possa farcela? Do you think that I can do it?
The subjunctive has a shade of doubt that the indicative hasn't. For example, credere (to think, to believe), pensare (to think), ritenere (to believe, to retain) all use the subjunctive case.
Io posso farcela. I can do it. "It is certain that I can do it".
Non credo che io/tu/lui possa farcela.
I don't think that I/you/he can do it. "It is not certain that I/you/he can do it".
Hope this helps!
