Hi Abhishek,
Not to worry. There are few good resources, which you can refer.
You have actually posted your query on one of these resources, i.e., GMAT Club.
Books & Other resources:
1. Sentence Correction: Manhattan is highly recommended though I haven’t yet seen it.
2. CR: Again Manhattan
3. Manhattan 6 set tests are also recommended for overall difficulty level.
4. GMAT Club Quant is very good. I have tried the free sample and it looks quite close to the real GMAT type questions. I haven’t tried the free Verbal sample. I hope that Verbal should be as good as the Quants one.
5. Besides, be active on forums.
You can also try few free practice tests. The links are:

Then there's one on this GMAT Club also. I have tried the Quant one but Verbal is still remaining. Quant was really good.
