Performance history available at no extra cost

The B2B Solution Architect premium membership comes with so many amazing features and my favourite is the performance history. This helped me analyze my performance and make a graph to track my strengths and weaknesses in different tests. I also reattempted the simulation of Salesforce B2B Solution Architect certification exam so that i could beat the silly mistakes and perform to the best of my ability. All this helped me achieve good score which was simply superb in my purview.
