MashAllah, this Qaidah was assembled wonderfully in that the color-coding makes it easier for students to identify 'merging' letters and basic rules which helps in reading The Holy Qur'an. The pages are also of very nice quality and the print if completely clear. I believe this Qaidah comes in two sizes but the smaller one is to my preference.
Personally, I find that this series is perfect for older students or those who are slightly familiar with The Holy Quran but want to re-establish the basics.
Only negative- it does skip over a few concepts that are included in other Qaidahs, but all-in-all a very good tool for learning The Qur'an.
