III semester syllabus is equivalent to A2.1 DELF(The DELF and DALF are diplomas awarded by the French Ministry of Education to prove the French-language skills of non-French candidates) which  is a grammar based test. So focusing on grammar should be your main target. That does not mean that you can take other aspects lightly. All delf exams consists of 4 parts. Listening, writing skills, comprehension and speaking.

For listening, you can use the CD (of text book) or  youtube to search for different kinds of videos in french. You can make a habit of noting down all the key words or phrases for the audio or  video for practice.

For writing skills, well…just write! Solve online exercises. I’m sure there are ample of them available on the internet and your workbook.

The same goes for comprehension. There are different kinds of comprehension books available online and exercices in your text book and workbook. You just might have to do a little bit of research to find them.

For speaking skills, when you have some time, pick up a topic of your choice and speak about it for 4–5minutes as much as you can. Auto-correction is appreciated. You must develop a habit of thinking in french and not thinking in english and then translating the thought in french. This is where we make mistakes the most.
