Hello again @Sidra,
thank you for sharing your question with us.
Some additional remarks with reference to my answer last week:
You could try an online course as well:
This offer is suitable if you intend to sit the TELC exam.
If you prefer Goethe, here is a very good collection of indispensable grammar topics and practical exercises from the University Passau, which will help you to boost your performance! https://deutschkurse-passau.de/JM/index.php?option=com_content&view=article&id=34&Itemid=165 (for all kinds of German exams).
And last but not least, one of my favourites: Deutsche Welle: https://www.dw.com/en/learn-german/level-b2/s-13230
Don't hesitate to come back to us if you have any questions. And try to do the mock tests I sent you last week!
