Knowledgeable and patient

My daughter had her first tutoring session for Chemistry with Maritess, she was very patient and detailed with her lesson. My daughter really enjoyed and was very happy with the method of tutoring Maritess has. She is in Honors Chemistry has had a hard time understanding the material, with just one tutoring lesson she said she actually understoood the material. We will continue to tutor with Maritess.

Delightful to work with and knows her subjects very well

I am a student who was behind in class. Working with Maritess was a good experience. She had no problem understand what areas I needed help in. She was able to teach at my pace and was understanding and patient. I wish she was my instructor for class.

Chemistry tutoring.

I like to set appointments with Maritess. As she answers fast, we can always count on her. My son, who is the one that gets the tutoring, likes the way she explains things and makes everything easy to understand. We will call her always when he needs help with chemistry.

Great tutor

Maritess helped me to catch up and understand Chemistry in only one hour. She goes through formulas step by step and explains what is happening rather than rushing through. Also she wrote down some important notes, formulas, tips, etc. that I was able to look back on while studying on my own. Very helpful.

Very Good Tutor!

My son is having great success in his chemistry honors class thanks to Maritess. He tells me everything being taught in the classroom is like a review because he is able to stay ahead of the class material. Maritess is very patient and will make sure my son understands the material before moving on. Her patience combine with communication skills allows my son to learn new materials quickly and effortlessly. I am looking forward to my son getting an A+ in Chemistry this year. If anyone is looking for a Chemistry tutor I strongly recommend Maritess.

Very nice and helpful

Maritess is a very nice, patient, and helpful tutor. She has a gentle approach in teaching the subject. She was very thorough in explaining to me the Organic chemistry topics that I was having trouble with. She also made me feel very comfortable when asking questions, or if I needed something to be repeated more than once - she was more than happy to do so. I've learned so much from her, and will definitely recommend her to any students who needs assistance in understanding the difficult subjects. Thank you very much, Maritess.

The remedy for all your chemistry problems

I sought Maritess's help 5 weeks into a 10 week quarter for my chem 121. I was in the D-/F+ range in week five and was able to finish out the quarter with a B- thanks to the tutoring sessions with Maritess twice a week. During exams, She offered additional hours for more tutoring if needed. My professor crafted all sorts of trick questions that Maritess was able to answer. There were some time consuming questions that she worked out right after the tutoring session then emailed them to me later that same day. I didn't understand the material my professor preached and Maritess was able to clarify any of my chemistry questions. I highly recommend Maritess to anyone trying to learn chemistry and I look forward to taking chem 122 with her help.
