The following recommendations provide guidelines for students wishing to gain the most benefit from their study using the program:

• Continuity is important.  The course is designed to be self-paced and self-guiding, so you may be working on one lesson session for several days or complete two lesson sessions in one day. It is important to work continuously and regularly in order to develop good learning habits that will stay with them throughout their education.
• Be flexible. It is recommended that a student should work on the course for 15-30 minutes a day.  However, there is a lot of flexibility in how you can use that time. You can choose to just do the interactive game during one session, and tackle the worksheets the next day, or combine both activities in each session until the designated lesson session is completed.
• Do not skip worksheets! All lesson sessions consists of an interactive program and a printable worksheet. It is very important to complement the interactive programs with the worksheets. They have been designed as a valuable learning reinforcement to further help students improve their reading and writing skills.
