HL / SL IB Chemistry Tutoring I am currently a Master's student and graduated with a Bachelor of Science majoring in Chemistry (First Class Honors, Dean's Honors List). I have been tutoring chemistry and physics for the past 4 years. I received top scores for HL Chemistry and HL Physics at the IB level as well as IGCSE level and am very familiar with the respective course content and testing style. I have brought my most recent student from a predicted score of 5 at HL IB Chemistry to an actual score of 7.
