It is human nature to increase the nervousness and level of anxiety by thinking negatively about forthcoming results/ time-bound events (specially things which are beyond control at that stage) because if the outcome is positive the amount of relief and joy is heightened directly in proportion to the self-created stress level. Every mother/wife goes through this experience when her child/husband is late in coming home or has failed to keep in touch when expected or is unreachable on phone for long time! No plausible positive reasons come to her mind for this except the bad thoughts. So, stop worrying.
If you have done enough to pass – nothing will change even if you keep on thinking every minute, ”I failed” except for increasing your mental and thereafter, physical misery.
If you have really flopped this time, what difference does it make whether you think “I passed” or keep thinking “I failed”, the email will tell you exactly by how much you failed before that it is mere guess (and second guess… and may be even third guess!). People who are sure they have failed do pass and on the other hand who are 100% sure of passing (and found boasting on AF) do fail. So, why increase tension and suffer?
You have done your best – now it is best to leave the result to CFAI (or God Almighty, whichever gives you more peace!) till they inform you whether your best efforts was upto their expectetions or not. It is one thing about which you can do absolutely NOTHING at this point of time, at least till you get the email from CFAI. At least enjoy the days till the D-day and then do the thinking either way. For now, as itera says, ”focus on something else” as distant from the exam topics as possible, passing the CFA levels is not the sole aim or purpose of life.
