Over all, my comments for all the problems:

Day 1:

1. Very easy and does not make distance to most participants.
2. Too tricky at the construction! Well, I hate myself for not solving it.
3. It’s eventually easy, but I am not used to do permutation groups. My bad.
4. Looks like a nice result.
5. Woh, Indonesian team has discussed this for case $a=1$. I thought that we cheat.

Day 2:

1. Easy one, but they cut me 1 point! WTH? (I blame this for taking me away from book prize)
2. Another tricky problem. In the test, I thought, what the hell with all these tricky problems!? I scratched for 3 hours, then just realized that it’s just few seconds manipulation.
3. I solved this in last 30 minutes. Not a hard one.
4. I was too paranoid for this problem. Very nice one, though!
5. I don’t care, even read this one (yet).

So, my test score for this IMC is 43 distributed as follows:

Day 1: 10 – 3 – 0 – 0 – 0

Day 2: 9 – 10 – 10 – 1 – 0

I got 2nd Prize with rank 75. The cut-off for gold is 50. No need to be sad, just be happy! 🙂
