A good thesis statement always works. And it’s for all time good practice to have a peer revision. Peer revision can be conducted by fellow students or mentor chosen by student. There are few points that need to be considered during peer revision.
1. Is the thesis appropriately punctuated?
2. Is grammatical issues are removed with proper sentences addressed?
3. Is there something like “they say or them”; if yes, then there must be some addressing to “they” or “them”.
4. The thesis must be extended to some supporting points. Elaboration and description of points is always a good practice.
5. Unclear or fuzzy words should be removed from the thesis as it creates a lot of confusion.
