Good blueprint. Chalk App is a very famous teaching aid software. However, the question bank of this software is relatively small, and the real questions from past years are incomplete. Moreover, it is not distributed according to chapters. It starts from large sections and cannot be detailed to each chapter. and small knowledge points, while the Blueprint app has comprehensive questions with detailed and clear content. During the teaching process, every knowledge point will be explained in detail, which is very attentive, so Blueprint is better.
