I studied Chemistry with Ulia 1 month , I needed prepare my gcse chemistry , but i didn't have time because before my exam I had just a few weeks, and I was depressed about my exam and now I seriously can't believe , guys, when we started I didn't have knowledges at all, actually nothing, because chemistry and sciences its not my subjects, this person really helped me in my problem with chemistry, now I've got level, we had really hard work with her, for me it was so difficult, sometimes I thought I can't do it, but she gave unreal motivation, she said "U can do it" ! Every time she talked about my opportunities, she supported me every lesson, she has really large experience and knowledges in sciences, she is incredible and so kind person, I really love her, and in future if I will have problems with chemistry I will studying only with Ulia, because she is the best ! my advice for parents who really nervous about knowledges of their child, who needs preparing for GCSE or for Russian exams or just u wanna know this subject u need Ulia! She is really the best on that website!
