621 Taken for Credit:Yes Attendance: N/A Textbook Use: It's a must have Rater Interest: Really into it Grade Received: N/A
"Get ready to read" "Would take again" "Amazing lectures"

The teacher is very passionate about Probability and very well organized. He is very helpful when I come to see him in his office. Tough homework but I am learning a lot in this class. A lot of students that were registered at the beginning of the semester did not seem to have the background for a 600 level course. I like this class a lot.

621 Taken for Credit:Yes Attendance: Not Mandatory Textbook Use: You need it sometimes Rater Interest: Sorta interested Grade Received: N/A

He was pretty harsh before the first exam, but after the last withdraw date passes and people leave the course gets easier. Lectures were interesting, but the assignments were difficult. The book isn't helpful at all, solutions to the exercises are not readily found online. You'll be ok if you know how to do all of the hw before the exams,

Math 120 Taken for Credit:N/A Attendance: Not Mandatory Textbook Use: It's a must have Rater Interest: Really into it Grade Received: A-

Coming to class was pointless as the professor basically read from the textbook and copied down the definitions and formulas he wanted you to know. He spent half the class going over HW, that can be taught to one's self. He is unsure of himself at times and takes a second to decide if he got the right answer. His grades are purely based on the test

MAT 241 Taken for Credit:N/A Attendance: N/A Textbook Use: It's a must have Rater Interest: Really into it Grade Received: N/A

Very clear and organized professor; definitely knows his material. Grades are based entirely on exams. Though his two midterms are very fair, his lectures and coursework do little to prepare you for the heavily-weighted final, which is exceptionally difficult, and has caused students that had been doing well to either fail or fall into the C range.

Math 621 Taken for Credit:N/A Attendance: N/A Textbook Use: Essential to passing Rater Interest: Sorta interested Grade Received: N/A

Very helpful professor who goes over the materials very slowly. The questions from the textbook are related to quizzes and exams. The only thing is: You need to have some good understanding of how the textbook represents the materials in order to do well in the exams. Otherwise, this course may not be the one you wish to take.

MATH 142 Taken for Credit:N/A Attendance: N/A Textbook Use: Essential to passing Rater Interest: Sorta interested Grade Received: N/A

This prof will work you really hard,if you dare not to do your HW at least 3 hrs b4 each class- don even bother to come to class- u'll fail. He teaches more than u need (lil annoying: summer's short anyway, and the material is already hard). curves the tests a bit. overall if u work hard u'll b fine- read the book, ask questions- he always answers.

MATH 142 Taken for Credit:N/A Attendance: N/A Textbook Use: It's a must have Rater Interest: Sorta interested Grade Received: N/A

Professor is very knowledgeable and willing to take the time to make sure you understand too. I must say he made calculus an enjoyable class, and I must admit that I always thought calculus is difficult. He explained integral calculus well. The material vas challenging, but the class was well organized. Best math teacher I had so far.

MAH1 Taken for Credit:N/A Attendance: N/A Textbook Use: Barely cracked it open Rater Interest: Really into it Grade Received: N/A

Dr Ralescu is a good instructor. If pressed I would recommend him. He does have some problems, though. His main problem is that there is a disconnect between what he knows and what he has immersed himself in as opposed to what the students might know or not know. He frequently runs rough-shod through the material at times confusing some.

Very clear explanations. True, exams are not easy, but you have to do the assignments. Don?t listen to those who are chasing good grades based on poor work. If you want to get an A without studying, look elsewhere. Dr. Ralescu is an excellent teacher. Highly recommended.

My request to all students who want to take Math 131 please stay way from him. He makes it so hard that you have to withdrawal the class, which I did. His exams are extremely hard. Stay way from him no joke.

MATH241 Taken for Credit:N/A Attendance: N/A Textbook Use: It's a must have Rater Interest: Low Grade Received: N/A

He's good & does the HW probs. 1st 2 exams were fine but boom! the final was hard. Hoped for an A- or at least a B+/B but don't know how ended up with a B-. He uses in class the textbook but some questions on the exams are not covered entirely in class. The subject is hard and hate the way how he totally switched from easy to so hard, not fair!

MATH621 Taken for Credit:N/A Attendance: N/A Textbook Use: Essential to passing Rater Interest: It's my life Grade Received: N/A

The midterms were easy. The final was totally different and was a curveball, which is disappointing, given one worked so hard on the midterms and only to get cheated out of a good grade on the final. He's funny at times and is willing to answer questions. Not a class for slackers, only for serious students.

He is a very good lecturer and goes over all homework problems. Good choice of textbook. I don't know why so many people are complaining that his exams are hard, because they are in fact fair-this is a master's level course in probability, by the way.
