I would recommend getting atleast gold complete before moving onto intermediate, since its a huge jump in difficulty. You want to be able to build good technique and have basic fundamentals, so you can then apply it to a harder scenario
Also, I would highly recommend playing the current season (season 3), since the scenarios address common weaknesses at the lower levels.
You can find the latest season on the Voltaic App or you can use the spreadsheet I have made for it (which has some extra features)
