I am wondering how to train skills fast during 2020. I am currently Level 190+ and my skills are lvl 30ish xD
There are multiple ways you can train skills.
1. Grinding ab repeat skills
2. Skill vouchers
3. Holy battlefield
4. Daily events
5. Newbie box(not same as growth box)
Might be other ways but for the most part these are main ways of Skilling that I know.
In addition, you should also work on getting items that give you 2x Skill EXP, such as, but not limited to, the League War badges (any lvl) and the Inspector Chinchilla Ride PD. These are just what comes to my head.
To add to what he said also:
6. League Farming (helps A LOT)
7. House Balls
