Section-Improvement Topic-Photosynthesis During the semester, the book was a hard thing for me to understand. Especially when it came to photosynthesis. The biochemistry was very difficult. The notes were simple and really helped in the improvement of my grades. The biochemistry was step by step and I was able to direct myself in the right way. Without them I would really have been confused and lost with everything that I was doing. That is why they helped me improve in biology throughout the semester.
