I assume this is the first map you have ever done. Not to be harsh it wasn't really well made. Here are some problems there were and things you should improve.

-Most of the walls and floors don't meet and there are gaps everywhere. I can see no reason for this so I just assume it's sloppy mapping.
-Talking of sloppy mapping, most of the textures are missaligned. I would highly recommend checking out lpfreaky's clean mapping guide. It should improve your mapping ALOT. Check it here: mapping-help/clean-mapping-guide-t5819.html
- Making your entire map inside a huge box just makes it bigger and run slower. If all the walls are made properly the box isn't needed for blocking leaks.
-The map is fullbright. I would recommend putting in lighting to make things look more interesting.
-None of the doors align with the walls. If you don't want to make a door frame yourself open one of the example maps Valve left and copy one.
-Neither the turret room and the boss room make no sence. You can just open the door and walk out. Also the boss just dies from one button press. Why not make people throw the core on lava or something? I honestly wouldn't recommend making ending bosses before your skills improve.
-Puzzles themselves were very easy. Not having a portal gun does make it harder to do good puzzles but it's possible.

This map doesn't deserve more than 1/5. Don't get depressed though. I'm sure you will improve.

Yes this is my first map And I dont know how to do a boss fight like from the game or the one you explained. Also the turrets fell over

guess you can say this is
