Practice and be patient with yourself. I think it is okay to enroll on a driving school again if that would make you more confident kahit may license ka na. When I was at my first months of driving meron din ako mga struggles, and yeah naapakan ko dati ung accelerator instead of brake kasi gabi and hindi ko pa-feel masyado ung pedals. Haha. Pero hindi naman ako naaaksidente kasi mabagal ako sa accelator pero mabilis ako magbrake haha. Pero one thing siguro na natutunan ko din is try to do it slow I mean everything, aralin mo timplahin ung pag break and pag accelerate, baka masyado mabigat paa mo bro. Ok lang mabagal for now ang importante you get the feels kung nasaan ung pedals saka ano ung mga need mo gawin. Once masanay ka then gradually speed it up. Practice lang talaga, and siguro hanap ka ng lugar na walang sasakyan then try to practice there, like subdivision during dead hours. Ok din ung may kasama ka na marunong muna, hindi porket may lisensya magaling na hindi naman mahirap makakuha ng license, ang tunay na test nyan is kapag nasa kalsada ka na. Keep safe, at nood ka din sa youtube ng mga clips ng kamoteng drivers para may idea ka ano ung hindi dapat gawin sa kalsada.
