Akiy.我们的课堂作业,帮忙改下语法、时态,

The final exam is coming soon. Have you begun to review all the subjects? For me, the most challenging thing is English because I did not work hard during the daily time and my vocabulary is limited. I have no idea about what I am going to do with this subject. So, do you have any valuable suggestions for me so that I can improve English in a short time?
Thank you so much for your help!
