Ways to gain XP quickly to level up

To level up in Skyrim it takes the following

Xp_to_level = (current_level + 3) * 25

then when you level up a skill you gain XP = the new level of the skill (so say sneak goes 56=>57 you gain 57 xp. This is why it takes longer and longer to level as you get to higher levels.

i just hit level 70 i bought the standard edition and now its saying specialisation complete and im gaining no xp. Is it a temporary xp cap or can i no longer level up?

The highest level you can obtain in Mass Effect 2 is level 30, it's no longer 60 as it was in Mass Effect 1 as they changed the way you level up in ME 2.

If you import a level 60 character from ME 1 for example, you will start out at level 5 in ME 2 and you will gain XP after each mission completed until you reach level 30; the limit.

Which is another change made from ME 1, in ME 2 you don't gain XP for each enemy killed or each crate/box/locker hacked/unlocked, instead you are only rewarded party XP at the end of each mission.

I know that I have Ambassador Status because the Specialization shows up in my profile (as a level 0), just not the XP or the option to include it in the breakdown. The Enforcement United shows up just fine in both, and I have gained enough XP from it to
level up to level 1 in XCL.

lol. too many butt-hurt kids with no other reason for living other than gaining XP on a video game. GROW UP. it's about having fun, not a race to max level. Go join the losers at BoostersHotline if you're so worried about gaining XP.
