Hi im soon to be taking the practical part of the level 3 2330 that has various tests you have to do and im wondering if it would be a worth purchasing guidance note 3 for information otherwise it will be a wasted
Got my 302 coming up soon, bought myself GN3 a few weeks ago, I'd definitely recommend buying it. It's more indepth than the info in the OSG, and the more you know the better - even if you don't use it.
Apparently the Adiabiatic equation has come up in 3 of the last 5 years' exams, so that's something to think about as well.
I only got my GN3 beginning of last year and im doing 2330 level 3 ATM and its already quite worn out. Most used book prob. Well handy to have. As said above a must for any training spark.
i got a disntinction in the testing and inspection part of my 2330 and didnt use guidance note 3. I'm sure in the written part we werent allowed to used the yellow amicus guides only the red ones and BS7671. However in the practical i guess you can use them we werent told any different.
I would have however bought one anyway if i could have deffinatly would have come in use more so than the 60 quid i spent on the regs book lol and onsite guide.
