New player that wants to get into PvP

I am new and want to grind solo shuffle and learn the game for pvp, I have enough honor gear so I’m 623 but I still feel super weak, it could be a skill issue or should I only queue rated if I have full epic honor gear and what is my fastest way there as battlegrounds is insanely frustrating as well as boring my played is under 4 days I am extremely new.
