getting back to the OP's question:
Hi, I am doing my D of E Silver expedition (3 days, 2 nights) and i was wondering if there are any tips or things that i need to remember? To make my time easier
Thanks!
My daughter is working on her bronze and probably about to register on gold so I can see a few pointers:
do not rush out and buy everything on the official kit list. Some of it is very sensible but some of it is over specified or weighs a ton, and some of it is borrowable or hirable from group organisers. Learn first then buy.
If you've not started yet: there should be expedition training courses run by your DofE operating authority, they'll explain a lot of what's needed. Join a group with others doing the same level so you can do all the training, planning and expedition together. Also, take your book along and get the course attendance signed up in the book (lesson learnt).
Discuss the kit choices here on the forum. Its plain from the overloaded DofE'ers you see on the hills that some of the DofE leaders do not understand the concept of "lightweight" and "DofE" in the same sentence. However I also suspect from previous threads that the reasons for some of the belt and braces DofE kit are not always understood here on this forum so make sure your kit choices still satisfy your DofE leader.
Use the expedition practice(s) to tune your kit.
Don't limit yourself to the official activities, do a bit of camping and local country walking with others. Practice the skills (map reading, cooking, pitching tents, etc). Learn from experience and get some confidence.
Rucksack - we originally bought a big heavy one at the local camping gear emporium recommended as suitable for DofE. We are now wondering if a smaller and lighter one may be more appropriate. The recommended bags weigh 2 - 2.5 kg, just for the bag.
Not on the official kit list - the universal repair kit (very small roll of best quality duct tape, 6 foot of cord and half a dozen safety pins) - can fix tents, torches, clothes, bags, boots, . . . 
Start collecting useful stuff when you see them (they won't be available when you need them) eg. small sample size tubes of toothpaste or suncream, or save up part used tubes.
Keep the weight down, be ruthless, don't take unnecessary stuff. A full new toothpaste tube weighs 120g (yes, she did pack it, because it was what was in the drawer, instead of the half used one next to the sink
, part of learning the hard way) - that's a lot of weight to be saved, not on its own but if 50g can be saved off 20 items that's 1kg gone.
eg. led camping lantern using 4 AA batteries, with 4 spare AA batteries, total weight 340g, - to be replaced with alpkit.com £12.50 headtorch with new batteries fitted before trip and spare AAAs, that should be about 160g.
Digital kitchen scales are a great help.
A clothing lesson learnt - avoid seams where backpack shoulder straps will be sitting, especially across the top and front face of shoulders. Get "raglan" cut tops.
Hope this all helps, we're learning so if anybody wants to disagree or add?
