Playing for about 5 hrs a day as a member you will probably have it by 2-3 days
Playing 1-3 hrs as a member will take 5-6 days.
Playing 8-12 hrs as a member will take you 1-2 days.
F2P is x2 the hours you will need.
*Botting is another way but I do not recommend it as you may get punished with a ban or stats lowered but its way easier to level up and you dont have to do anything.
This entirely depends on what level you are starting at and what you are using to train the skill.
Depends on your Woodcutting level, what axe you are using and how long you play per day.
About twice as long as it took you to reach level 87 from level 1. Each level requires 10% more experience than the previous level.
It depends on your woodcutting level and what hatchet you use. It can take from 10 minutes to 30 minutes depending on that.
This depends on alot of things, Your woodcutting level, If you are going to buy or cut them, How long you play Where you are cutting them, But usually it would take about 2 days to get 2k magic logs
Pressumably, you already have level 76, so you would have an estimate how long it took you to reach that level. It should take you about 8 times as long to reach level 99 from level 76, since in total you require about 9 times as much experience.
It depends on the average hours you spend wc'ing a day.
Go to runehq.com they will tell you everything you need to know.
depending on how often you play runescape and which method you are using to level your woodcutting, you should approximately gain 50-100k experience per hour, therefore it should take 130 hours of game play to achieve level 99. however if you are not gaining that much experience per hour you can gain a rough idea of how long it will take you to reach level 99 by knowing that level 93 is half the experence needed to reach it, so you know your half way.
You can be still looking at a good few months there, it's hard to get a more accurate answer.
I bet a few hundred people are pondering over how long it will take. From 78 Woodcutting to 99 Woodcutting can take from months to weeks, depending on what you want. You either can go for Money or Experience; Ovbiously everyone would want Money, However! The money way will take any where from 3months to a year. The easier route (That would make more money in the long run) is Ivy the 2009 Update, currently the fastest way to 99 Woodcutting. Requiring 68 Woodcutting, it is VERY popular. This is the best route.
you will be looking at around 6 - 8 months, maybe longer.
