I have only just lately been using the "Efficient Levelling" advice - and what I found was best to do is create a chart on notebook paper that groups the skills that have common attributes together, with the major skill (which will increase main levels) listed first in each group.
I also list the attributes in a section at the bottom of the page, so that at a glance I can track what is going on with each - and plan better where I want to go next.
This makes a chart with seven groups of three skills each, and eight attributes at the bottom.
As I go along, I place coins on the skills that i am working on. Since the chart is numbered across the top in columns up to ten - I can advance the coins across the page as each skill is advanced, so to keep track more easily of where I am at, at any given moment.
I have been thinking of connecting one of my scanners to my new PC sometime soon - and when I do perhaps I can show you directly how it all works out.
From what I have done so far - it seems almost impossible to nail down an "EXACT" efficient levelling - there is always something that comes up. Fortunately Restoration for one is a difficult skill to build up, and so using restoration spells along the way doesn't necessarily harm the effort in any material way.
I try to make the harder skills to build up my major ones, so that they will not build up unintentionally.
AN exception to that is "SNEAK", because in the early game it is very helpful to use it as a means of making a major level (* I think of the different levels as "SKILL-UPS" and "LEVEL-UPS" for simplicities sake).
Because of my intention to gain items enchanted with CHAMELEON at the earliest possible moment - I chase down the three skills CONJURATION, ILLUSION, and SNEAK right from the very beginning, making them a priority
Conjuration is one that I run up fast - because summoning Xivili's (or however you spell it) to kill with a weapon of SOUL TRAP is the best way to get grand soul gems filled - and I also go right after AZURA's STAR!
Summon Xivilai is very expensive in Magicka unless you have Conjuration 100%'ed out...
At level ten - you can also go get the Nocturnal quest out of the way - and this gives you the only lockpick you will ever need...
The real bad one though - is the quest for Meridia. The bonus from it is priceless. But the necromancers in Howling Cave are seriously hard to destroy.
THIS is where you gain the Ring of Khajiit - and do not ever try to put it in a chest in a house you own! You'll never see it again...
