Should I or Shouldn't I?

Omigosh! I'm in a dilemma right now! Can't take this anymore! Okay, here's the story..
I really wanna go to a seminar of how to answer and tips about scoring 'A' in our big government examination [PMR].. However, without being planned, a letter had just arrived yesterday and was given to us today. It's about the upgrading of the scout. I thought the date was written as 17 October 2011, but when I look back,.........OMG! Darn it! The date falls on the same day as the Seminar Score 'A'! Oh my Louis Vuitton!

Well, I thought I can attend both, but when I saw the time to register, it's at 1pm - 2pm.. I nearly fainted! WHAT?????? This can't be! The Seminar Score 'A' starts at 9 a.m. and ends at 4.45 pm! How can I divide myself to attend two events in one time? No. I can't do this! Priority comes first, so........which one is my priority?

IF I go to the Seminar Score 'A', I will get more tips and knowledge for the upcoming PMR since the countdown to PMR is only 3 weeks to go (including this week)! I had try my very best to score 7A's, but my current achievement is around 5A's.. So, if I attend this seminar, maybe I can get many tips to score better in my examination..

IF I go to the Scout Upgrading Camp, I will not have to go to Co-curriculum 2 days in a week.. I will get my upgrading badge faster and my friends are going to the camp this Saturday too.. I will have friends there and I will not feel lonely because I know most of them who attend that camp..

Now, I've got TWO choices! The camp or the seminar? I'm in dilemma right now!

My dad told me to leave the camp-so-thingy aside and attend the important mission before I proceed to the WAR..

However, my teacher told me to attend the camp, so that I will not have to attend for co-curriculum activities for 2 days in a week and I will get my upgrading badge faster..

So, what do you think?
