How to get good

Finding a high-IV Pokémon is a process that requires patience. First, consistently do raids and field research. If you keep at it step by step, you'll surely get good results, hmm!

I'm new too, so I don't know.. I only do raids with pros.

Do you do a lot of raids?

To catch good Pokémon, you need to do a lot of raids and field research, as the people above mentioned. Also, if you consistently catch wild Pokémon whenever you see them, you'll find yourself catching good ones before you know it.
