I wouldn't worry at all, just take it as it comes. The time allocated for a type rating is sufficient to be able to pass the skill test. I'm now just finishing a Boeing type rating myself (flew a turboprop before), had no problems whatsoever. The only tip is focus on company/ Boeing procedures and not the technical knowledge - I tried to reaally study the CBTs and systems, however in the end ran out of time and still forgot a lot; technical knowledge is necessary, but will come with time, so don't worry.
Most importantly, enjoy it!
