Hi Vidyuth,
I took a look at your Manhattan CAT. Since you’re just starting out, it’s hard to get incredibly specific on what to work on, but here are a few tips:
1) You’re finishing both Quant and Verbal with lots of time to spare. You may want to think about slowing down to work more carefully on some problems. However, it’s not unusual to finish a bit early on your first exam, because there are some problems you have no idea how to approach. You may actually slow down as you start studying, because you will know how to work a larger proportion of the problems.
2) You need some explicit practice in Data Sufficiency. Right now you’re missing most of the problems of this type. This is not too unusual for a beginner, but this should balance itself out as you go forward. Make sure you get familiar with how to handle DS right away, so that you can comfortably use DS problems for practice as you study each math topic.
3) You are very unbalanced in your math performance. Some areas, such as geometry, are very high, while others, such as algebra and word problems, are so low they’re nearly random. Make sure your fundamentals are strong. I recommend our Foundations of GMAT Math book for that. If you know how to handle all the basics, it’s not too hard to put them together to handle tougher problems.
4) Your Sentence Correction needs a lot of work. This is not uncommon for non-native speakers. I recommend that you work through our Sentence Correction strategy guide slowly, chapter-by-chapter, building up notes and key strategies as you go.
5) Another key verbal skill you need to work on is inference. This comes up in Critical Reasoning (Draw a Conclusion) and Reading Comprehension, and you’re getting hit pretty hard right now. Make sure to read up on inference and practice this extensively. You can’t get a great verbal score without good inference skills!
Good luck!
