At first practice your jungling routes and pick on you like, check your timers on both sides, so you know where enemy jungler is and can warn laners if you gona be late for gank/countergank grab early ward proceed to farm or gank, personally, with new jungle, i find it better to ward and simply farm come for counter ganks than forcing yourself ganking, if you fail em you will fall behind fast, i mean fast, its not uncommon to be lvl 4 when sololaners lvl 7 already and most midlaners demand second blue at that time or just come and blatantly steal it from you further setting you back. Going afk for not giving blue is very common...
So watch some youtube videos with analysis of new jungle, do some normal/draft games in the jungle then go ham in rankeds.
Few things:
- Goto gank only when opponent is open for taking, dont force yourself with ganks, you will fall behind if you get nothing out of it
- Lvl 3 ganks (1st gank at min 3-4) are most impactful and risky
- Farm your jungle first, then go look for trouble, if none to be had place defensive ward for your laner and move on
- Buffs are yours as long as you feel like you need them, jungle is unforgiving
- Come to hold towers when laners need to go back, tell them that and tell them when you are free to do so or tell them when they have to go back (im very bossy)
- Watch the map whole time when you clearing camps, moving around, buy wards ping for misses, issue warnings if you feel gank is coming
- Dont rage
