What users say
Pros
- Math and science lessons have carried college coursework through calculus, chemistry, and organic chemistry.
- Worked explanations rebuild forgotten algebra and calculus foundations after long gaps.
- Formula derivations add conceptual perspective beyond memorization.
- Self-paced coverage spans foundational math through linear algebra and differential equations.
Cons
- Instructional examples can jump from simple practice to substantially harder test questions.
- Hints and repeated videos provide limited guidance when a difficult question remains unresolved.
- Videos can feel slow, repetitive, dry, and distracting during longer study sessions.
- Answer checking rejects valid responses for capitalization and formatting differences.
- Advanced STEM coverage lacks depth for niche cases and rigorous problem preparation.
