Hi...i scored 618.50 (75.62%) in mat dec17 & my comm. skills are not that good...can i get good college at this score???

First of all Shruti in the MAT exam your percentile is not that good so getting a very good b-school like IFIM, ISBR, ISME, Christ or XIME will be a little difficult. Still, if you have a strong profile then below I have mentioned some of the colleges where you will have a good probability of getting a call and convert it with a good performance in the second round of WSAT and interview:

• BIMTECH Noida for their- PGDM (Insurance Business Management) and PGDM(Retail Management), MAT: 75+ percentile
• Christ College Bangalore- MAT(Dec and Sept), MAT score: 600 and above, 75+ percentile
• Gitam university- Vizag, MAT: 70 percentile
• Gitam School of International Business, MAT: 70+ percentile
• IIRM Jaipur, MAT score: 500-600, 65+ percentile
• ITM Navi Mumbai, profile-based
• IPE Hyderabad, MAT: above 50 percentile
• NDIM Delhi (all programs), MAT: 50+ percentile
• PSG Institute Of Management, Coimbatore MAT score: 600+, 70+ percentile
• SIES College of Management Studies, Navi Mumbai, profile-based

And also you need to work out on your communication skills otherwise even when you get a call from any college for second round of GD, WSAT and PI it will be very difficult for you to fetch good marks and that will hinder your admission process because generally interview marks carry highest weightage in the final merit list.

All the best!!
