The best way to make progress is join/follow the online class.
Come join Oracle 11g SQL class, you will be OK.
Start with Access 2007 course is OK too, but the last two chapters are not easy for new students.
After take Oracle SQL or SQL Server SQL, Access course is relatively easier to follow, this is the conclusion from most of the students.
Yes, After Oracle 11g SQL class, othere classes will follow.
Yes, several hundreds of our Chinese friends have found excellent Database Analyst jobs all over the world after take our training program, they made a life time change which is impossible before.
Thanks.
