Question regarding rate of character progression
 

I have about 50 days to play between now and when the school year starts again. If I have a level 7 SK, how far can I expect to get? (Mostly in terms of level)

How many of those 50 days will you actually play and how long each day?

Will you be power-focusing on maximum xp gains or enjoying the ride up?

Your question as it stands is impossible to answer. You might make it to level 9 ... You could theoretically make it all the way to 60.

It took me 7 months to get to 60 but I'm casual scum so it just depends on your play time. Are you playing every day all day for 50 days?

Well, I have 90 actual days, but those 50 days are the days I plan to play all day. However, I am a casual scrub who would focus more on enjoying the ride then maximum possible xp

youll probly get mid 40s low 50s unless you go hard

Ok

you don't have the hybrid penalty anymore, if that's a boost to your hopes :)

30's to 40's probably. A level a day is pretty hard core.

In the Early levels id say that entirely depends on your knowledge of the game / class you pick, some classes hit the ground running and some are late bloomers. However i do agree on average a level a day is a pretty significant commitment

If you're playing all 50 days most of the day(8 or more hours) AND you know what you're doing AND you focus on leveling, I see no reason why high 50s to 60 isn't possible.
