You won't get penalised for using the calculator and simply stating the result - unless of course the question asks you to show your workings.
But if you make a mistake your result will be wrong and you'll get zero marks for that result. If you were to do the calcs manually and wrote the steps involved as well as the result....but made a small error within the steps...you might still get some marks. Especially if the examiner can see that overall you understood the question and the formula required, made a minor error on only one step and can see that the rest were followed through correctly.
I was using the BA2 for my first few exams and then changed to the fx-85. When I wrote CT1 I preferred not to rely on the BA2's annuity and amortisation functions so simply didn't use them. I personally much prefer the fx-85 for two main reasons: a) it produces results as a formula similarly to how you see them in the CT1 notes and exam papers. For example 2.35*5 = 11.75 but the fx-85 also gives this as 47/4. And b) the stats mode on the fx-85 allows you to easily do interpolation; very useful for the standard-normal distribution probability q's in CT1 and significantly more so in CT3. Just my thoughts!
