Those are some pretty good guides, but i hope i was of some sort of help! good luck on 99 range!
Simple. Just keep training. Some good monsters to train on are Rock Crabs (Lv. 13) and Experiments (Lv. 25). These monsters are good to train on because they have low defense and attack but have much health. Thus, they provide much experience and you do not have to worry about dying. Experiments yield 400 experience and Rock Crabs yield 200 experience.
Every skill in Runescape needs the same amount of xp to get to lvl 99. The xp until lvl 99 in ANY skill (including Range) is:Approximate: 13,000,000Exact: 13,034,431So basically 13mil xp. ;)
The total exp is 13,034,431 experience for a 99 stat on RuneScape.
There is a girl that has 99 on all skills her runescape name is 'xxphatmagexx'.
