To clarify I understand this right, provided there are not other cards moving your tokens around, the possibility is...
In Spring, +1 Action +$1
In Summer, +2 Actions, +$1
In Fall, +2 Actions, +1 Buy, +$1
In Winter, +1 Card, +2 Actions, +1 Buy, +$1
And I presume the first time you play it in a given season, you don't get the token bonus because it was not on the student pile when you played it?
If I did read that correctly, then this sounds like the pile will be a mess covered in all those tokens. It might be advisable that they go onto a mat or something.
It seems like a bit of a late bloomer. The effects of the card are not really "worth $3" or more until Winter. And to get it that good you really need to have stuck with it from the start. I like it conceptually, but it feels like it needs a buff.
