I think there's sites that are meant to do that for you, that's probably the best route for you. I'm GE myself but I can't see myself giving many more tips than just saying that you should play 2Hours of Deathmatch every day. But you should watch streams though, ALOT of streams. Tournaments and solo streams. I prefer Summit1g. Go on Google and type in CSGO bootcamp. If the link that's first is from reddit and has something about BETA in it, click it.
