Vedic . . .
Vedic, not verdic, astrology generally refers to related methodologies that are practiced in India. A 'sidereal' zodiac (fixed star based) is the basis of planetary positioning unlike the more common 'tropical' zodiac (seasonal based) used in Western astrology. Cyclic tables, many complex terms (from the western point of view) and rules form much of the practice.
As with any astrological system, Vedic or Joytish astrology has its proponents and detractors. If you at the very beginning of your astrological explorations and if most of your contemporaries are western/tropical oriented, then I would follow their practice as it will make it easier to find help and resources in the relatively complex area of study. Vedic astrology has been adopted by a significant minority here in the US as has the many other methods of practice.
The best advice I can offer you is to initial stay mainstream, don't get caught up in trends, shortcuts or advanced subjects until you have all of the basics well understood -- a solid grounding will support your later adventures. And plan on taking five years or more to study and learn the major branches of astrology -- and that will include reading and understanding and using the knowledge from some 50 to 100 books and casting of hundreds of charts.
