Well, sad to say that these kind of "experts" are everywhere... I don't mind if they keep quiet when they know that they're illiterate in a certain field... but the same cannot be said to those who act like they do when in fact they don't

Unfortunately at this stage you can only play safe and let it be, this is how things work over here (assuming you're in M'sia) People take things too personally if you do voice out and challenge his/her competency.. You have to make sure that you graduate first
