A.L.S. or Alternative Learning System is a program that our government offers to the people who didn't finished their schooling due to to some personal issues that they may finish their lessons without attending regular schedule of classes. It can make a benefit to you if you have any problems like financial problems or psychological problems.
If you are forced by yourself or parents to stop your studying at school due to something or otherwise, you can still continue your studying without going to school everyday. So if you are planning to join A.L.S., make sure your decision is firm so do your purpose and reason. Whatever your decision is, I know that you can still find the right decision with the help of God, of course. I hope this answer is useful to you, God Bless
