This place is fantastic. I started going to OAT in the summer after grade 9 to learn grade 10 math. I did exceptionally poorly in grade 9. Over a single month Hamed was able to undo the damage done by the previous year's teacher(s) as well as fill in a ton of gaps in my math knowledge. I have taken every math and science course there and they have all been exceptional. I will for sure be taking the rest of my stem courses at OAT. I really can't recommend them enough. The class sizes are very small (4-7) and the teachers are very flexible in their approach. You never feel afraid to ask questions or say you don't know something. Teachers are also very reasonable about deadlines.
