One of the absolute worst professors I have ever had. I'm a straight A student and I had to drop the class. The man is totally ridiculous (in a bad way), speeds through the material and doesn't explain anything that he is doing. When I asked for help, he told me I was on my own. If you are smart you will avoid this professor at all costs.

You enjoy failing courses? Go for it.

This professor teaches the material decently but his tests and homework are ridiculously difficult. Even if you study for days you will still fail his class. His hws go beyond what should be included in the syllabus and they make up a large portion of your grade. He expects all his students to fail and does so, don't recommend this professor.

Don't even bother taking him. Exam questions nothing like what was went over in lecture. Opportunity for partial credit only on 25% of entire test, but you have to give a near perfect answer. Assignments are even worse so you won't even have a chance to make up if you mess up on the midterm or final. I got a A in the prerequisite course(CSCI 120).

He is not a good professor, because he goes over the material really quickly and also the exams were really tough. he doesn't believe in partial credit,so if you can answer perfectly then go for it, else stay away.

Please stay away from his class he will ruin your gpa.

His exams are tough , very TOUGH !! and he seems to enjoy to see his students struggling to solve them. He is kinda evil. For real. Take him, you'll see. And get ready to take it again. His classes are dynamic and entertaining that's for sure... but when the tests come.. the fun is OVER.

Professor Boklan is the most rude and arrogant professor I have seen in QC. Never respect his student. The material is okay before second exam, after that everything is going to aspect. The average score for every exam is ranged to 45-55. If you are good at math, most likely you will pass the course with a C or B-.

3 exams, get 50 each you will pass. Exam is extreme hard. Very rude and no respect to students at all.

The worst professor I have taken at QC. Never respect students. Avoid him and switch to professor Obrenic.

He gives grades based on his personal preference. I reported him to CUNY Undergraduate Scholastic Standards Committee (USSC) abut this, one month later, he reported me to QC behavior team. But it was ok because he has no evidence. Report him if you have no choice to take his class and get an undeserved grade.

Don't late for class, otherwise you will be shamed. No respect to students, no asking questions.

The lecture was ok, but the exam was extremely hard. Avoid him.

Tough grader. The exams were difficult. If you work really hard, you could probably pass with C because this guy will give you hard time and enjoy it when you are struggling.

Tough grader. Knows how to teach but his style is just old fashioned. His test questions are extremely hard, which you have never seen in the class.

Worst professor ever at QC. A arrogant guy.

He starts the semester telling you not to believe what everybody else has to say about him. Unless he changes that whole shpeel, just go to a different professor or drop him. He's not worth the struggle. He is intelligent and has the attitude of RDJ's Iron Man/Tony Stark so that should tell you what you'll be dealing with.

DO NOT TAKE HIS CLASS. Extremely tough papers and he tries to be over smart.

Not worth it

He's just so so bad. Do yourself a favor and never take his classes. Assignments and exams have nothing to do with what is taught in lecture or textbook. Loves failing people and giving zeros, discourages you, is extremely harsh and rude, refuses to help you, AND makes the class almost impossible to pass. DO NOT TAKE HIM. Not worth it at all.

Cares more about punishing students, catching them for teaching etc. Kent, I know you read these, maybe if you spend all that time actually teaching and making sure students understand instead of penalizing them, your students will be intrigued and want to learn. Looks like youre showing off that you know how to do it be actually teaching. FU!!!!!

Just dont do it. I never felt met a professor more arrogant in my life. His tests are insane and youre guaranteed to have a 90% chance to fail his test. Harsh grader. If you make a little mistake on a problem (Ex. Not adding a star) all of your points is gone. Dont listen to any positive review about him. Dont take him for 320 and 220

I dont mind the hard work but his attitude is the worst ive ever seen and grades so bad that you get all the points off for a tiny mistake. He is not understanding at all and spends most of the time talking about topics that wont be on the tests avoid him!!

JUST DONT DO IT! He gives problem even he has difficulty solving and calls them "interesting". He's more worried about catching you cheat than teaching you. No partial credit! He gives himself good reviews on here to trick you into thinking he's good. I promise you'll regret it if you take him. 220 is hard but with him it's almost impossible. DONT!

There is some professor who wants you to do good in the class but I feel he literally wants to fail the whole class. The most terrible professor I ever had. No matter how hard you study he will only give you bunch of zero's in his tests. No partial credits at all. This class is not that hard but he makes it look like a NASA project.

Very little feedback, huge ego. Go to all office hours and practice a lot. Never gives partial credit

Professor Boklan is by far one of the worst Professors I've had. He has a passion for what he teaches but he HAS to understand many students do not share that passion. His exams are ridiculously difficult and he always says "iF yOu sTuDy ThE tOpiCs eNoUgH yOu'LL bE gOoD". No one has the kind of time he imagines we do.

His head is so beautiful. He will make a better next generation of Mr. Clean than as a professor.

Very difficult. He will make your brain hurt. He doesn't care about you trying. Wrong answer and you get a zero. Very tough grader. Don't expect him to curve. He'd rather fail you then help you.

Test are impossible

take this class with him if you want to delay your graduation.

He gives good lectures but exams are impossible. He cares more about cheating than give a proper exam. Gives 3+ pages with only instruction on how to take the exam, something simple yet he makes it that complicated. This are just the instructions, imagine the exam, too long & no time, even the short Q's. I can go on but can't so read other reviews!

He's very bad. Just don't take him. I took him for a second time because I had no other choice and now I wished I just sat out the semester. Literally cried because of this class. 90 people took the class and 20 passed. A pass is a 45(C+). Let that sink I. 70 300 level students could not get a 45. Think about that.

Passive aggression in the form of a person. Complains that students don't use office hours and takes up a third of the class on it. Pop quizzes meant to throw you off and tests are "fair" is what he would say. It's only fair if you get lucky and get the easier questions first and don't get time gated for most of the test. Overall avoid.

Pretend that this "professor" don't exist. He's a former government official, so in other words "corrupt". Probably left the NSA because he was not smart enough so he tried to flex his intelligence to a bunch of teens and people in there early twenties. It's impossible to defend this "professor" as he only cares about failing students for his ego.

This man's ego is so huge that he actually bragged about his failure as a professor to his students.

Hilarious, in the first week of class he said all that was needed was 20 minutes a day to do well in his course. Less funny was in office hours, when he said to a student "Go ahead, write in chat so we can laugh at you because you're wrong". Being hard is fine. Boklan, however, also seems not to want his students to succeed. 98 enrolled, 11 passed.

I worked very hard for my C. What was disappointing was that Boklan said a lot of things that were encouraging and made sense, but when it came time to actually answer questions or give feedback he preferred to make students feel dumb. Exams are hard for bad reasons: wall-of-text instructions, bizarre formatting intended to confuse, time crunch.

1 error on your work, and it's already over. If he tells you not to read the reviews because "they're not true", it's because it's quite the contrary. The negative reviews are VERY true and to the point. Any "good" reviews are either by the professor himself, or someone who's coping. If possible, take literally any other professor.

DO NOT TAKE THIS PROFESSOR! Grades are only determined by 3 exam each worth 33 points except the final being worth 34. Need 45 points to pass with a C. In my opinion, grading criteria is fine but EXAMS ARE A LOT HARDER than what you learn in class. NO CURVE whatsoever and brags about students dropping his class. Ive put so much effort just to fail

There are 3 exams and the exams are so hard. Prof said pass at 20 out of 33. But the students have a hard time getting this 20. Enrollment was 93, all of them drop except 14. Never take his class.

Take him if you are GOD gifted talented. DO NOT TAKE THIS PROFESSOR! Grades are only determined by 3 exam each worth 33 points except the final being worth 34.

"Prof Boklan is a top professor at QC, but only if you accept that you WILL work for your grade. His lectures are very fun to listen to, you need to take good notes. It's classes like this that build character, and create memories that will last long after you graduate. KDB expects the best from his students and tries to force that out of you.-HAHA

prof boklan is by far one of the worst prof i ever seen at queens college. not only is he a terrible chair for the college as well, his teaching are terrible and is a horrible human being. I had asked him if i could somehow make up for an exam due to one my family members passing away and he gave the worse response ever. DO NOT TAKE HIM

It is so frustrating being in this guys class. He teaches well, but his exams are such a pain. He makes it harder for no reason. He's a wannabe MIT professor, teaching at a CUNY. 45 is passing in a 300 lvl CS course, that really says a lot. Not worth taking this class with him.

Boklan is the definition of everything a professor should never be. He discourages you, laughs at you, embarrasses you. Every lecture was an hour of listening to him complain about his wife and brag about what he knows. Asked him for help, he said nothing but "stop overthinking."

This lightbulb looking guy thinks he is a god. He does not care about you whatsoever. He genuinely enjoys seeing his students suffer. He needs to realize this is college, not the military. Perhaps he needs some therapy to sort out his childhood issues.

Do not take him. He will also say do the homework's and study at least 30 mins everyday to pass. Trust me yowl think everything is okay until you reach his exams. His expectation is so bad, expecting us to solve problems like him when he has been doing it for about 20 years. Just take the class with someone else

Lol this guy still writes his own reviews? Do not take this class. Good lectures, but those exams are brutal for no reason. He makes those exams way harder than they should be. Teaching to ruin students confidence, that's really what he does. And he says don't believe the reviews, but that's complete bullshit. Not worth the stress and pain.

Worst prof at queens college, will expect you to know everything before his class, does not teach and does not care to teach, reads everything from a textbook without knowing a single thing

Every decent review you will see on here is faked. Cannot emphasize how difficult this professor made my life. I am just telling you take anyone else please. And he doesn't turn a D into an F. He keeps the grade that way because he is trying to gatekeep computer science.

he is there to hurt you not help you. avoid at all costs

Worst professor ever. This guy is everything a professor shouldn't be. I am not sure why chooses to teach. Please avoid at any cost

He is faking his reviews. He makes everyone's life difficult. Avoid at all cost. Take literally any other professor in the world.

if misery was a person, it would be kent boklan.

Don't do it! wait a semester if Obrenic is full.

Boklan's course is very old-fashioned. No electronics during class. He will not respond to emails. There is no curve (73 is A). There is penalty for guessing True/False questions (2 out of 4 answers correct results in a score of zero). Treats students as kids, chastises latecomers, few partial credits, and enjoys deriding students. Very fast pace.

He is getting reviews taken down and putting up fake reviews. Here is my word of advice do not take this teacher no matter what. No matter what school, no matter what class. Dont take him

Absolute worst professor I've ever encountered, ask anyone in cs and they'll give you endless reasons why he made their life miserable

Good reviews are fake. Please stay away from this professor. Take another peofessor or this class equivalent in other college and transfer credit. I was sick and he told me that I have to take exam no matter what. I couldn't study and failed. See other reviews and stay away.

No matter the time put, you'll most likely fail. If you want stats, the highest Avg of a Sem was 1.89 and the lowest was 0.76. The class is entertaining and he teaches well, but his problem set is extremely difficult as are the exams, with little to no credit for any work shown. You'll be happy getting higher than 25% on a problem set. Wait a Sem.

This CS elective of Cryptography is treated like a masters level course for just 3 credits. Anyways he tells us to drop due to the workload and he says people before have taken time off their jobs just to work on the group project at the end.

Don't take even if you're thinking that "this is the semester I put my mind to it" cause even then, you'll fail. Boklan is smart, but he isn't a good professor. He lets you know that this is the most challenging class in all of QC but fails to tell you that he is the reason its hard, not the course topics. Only 1 person ever got an A+ in this class

This professor follows a flawed philosophy where high failure rates equals "rigor." Instead of teaching effectively, he seems to actively gatekeep success, believing that if most students pass, he's too easy. In reality, the high fail rate reflects his poor instruction, not student effort. Avoid if you want a fair chance.

"There are no bad students, only bad teachers" - Mr. Miyagi

Be wary of the glowing reviews; they don't reflect the reality of this class. The teaching was poor and the syllabus was ignored. My experience was the polar opposite of the high ratings here.

Theory of Computation is a challenging subject, and the course structure did not make the material easier to grasp. The teaching style was not a good fit for me, and despite completing the homework, studying extensively, and attending office hours, I struggled to succeed. Avoid, he fully lives up to the reputation people warn about.

Napoleon comp. who makes the material much more difficult than it should be. Best ways to explain the lectures is a subscription, where you have to attend office hours to get the rest of the “product”. Because he quite literally tries to force you to attend office hours and refuses to elaborate on some of the material
