A good base in complete from scratch basics is duolingo. As you go along write down explanations and whatever notes seem necessary. Also, try lingq! It keeps track of vocab that you do and don't know and the content is interesting. Other than that I really suggest that you try to discover what works for you. I jumped from A2 to B2 in French by trying to live my life in French. Thinking, writing etc. Something that helped me a lot was writing my thoughts out in French and then discovering gaps in vocab and filling them. That urgence to remember an important word helps me to memorize them. Other than that just get plenty of exposure. Find a regular practice partner. :) that also helped me a lot was trying to communicate. that's what language is about and when you're trying and people aren't getting it, you want to try even harder and improvement comes fast. :) Find what works for you though and good luck. P.S. YouTube helped a lot too. I watched an interview in French and could barely catch a word. Several months later I rewatched it and I understood almost everything. It's great for tracking progress
