Am i alright for my level in wizard101? (its kinda long but plz read all)?

ok i am a level 38 magus diviner (storm) in mooshu on wizard101....i just got to mooshu yesterday at level 37 (almost level 38).....my health is 1760 and i have a little over 200 mana....for me wizardcity was pretty much easy just a couple of battles were hard towards when i was finishing it....krokotopia was very long and a little hard at the beginning and end....the middle was fine......marleybone was easy for me except the dungeons ( katz lab, counterweight west)....now im at mooshu and im afraid i aint quite ready for it....i just did the shiraki temple and it was really long and hard when i got to wavebringer (the first try it was me and a myth.... 1134 health....lvl 23 and we both died...then on the second try it was me.....the same other dude and another guy who was balance....lvl 35-40 and i forgot the health but it was near mine....i almost died then i came back and the lvl 23 almost died (i think he did at the end) and the 35-40 guy was half way out of health.....also the boss and minions were all storm...then the next two battles were easy because the bosses werent storm.....is mooshu all like this? and am i quite ready?
