Ask HN: How did you get avg 95% in University?

In my experience, it's surprisingly easy to get through most classes without doing the recommended / assigned reading for a course. Often, the professor will basically go over the same material in class as was covered by the reading, so if you didn't do the reading you'll get the material in lecture—alternatively, if you do the reading you can get away with not going to class.

If you simply do all the reading for a class (a couple of days before the class session, so it has time to sink in), you'll be much more likely to absorb all the details the professor mentions in the lecture, or that you missed the first time around in the reading. You'll also be ready to ask more informative questions, that will get help you get ahead instead of catching you up.

Other tips (some might seem obvious): keep a notebook where you take notes on the readings and the lectures; review the reading with your notes shortly after the corresponding lecture; go to office hours if you don't understand something or are having trouble with a homework or programming assignment; start homework assignments as soon as they're assigned (especially for larger projects); plan on spending twice as much time as you expect on homework / projects.

If you keep up (or keep ahead) during the course of the semester, you shouldn't have to work too hard to study for the exams. Use whatever study guides (or hints about the contents of the exam) the professor gives you as a guide, and make sure you understand all of it. If you don't understand something, take advantage of office hours to get help.

There is also strategy to taking tests well. Some tips: skip a question if you don't know how to answer it right away and answer it later; show you work or explain your reasoning so that you might get partial credit even if you get the wrong answer; if a question is unclear, go ask the professor for clarification; often times questions later in an exam will give hints as to the right way to approach questions earlier in the exam; get plenty of sleep the night before, and a good breakfast and coffee the morning of; don't worry too much, because worrying won't help you to perform better.

I handed in 50% of the homework and got 100% on the exams. Most courses I took had 10% of the final grade based on homework.

And no, I didn't study; but I did read the textbooks cover-to-cover before the first day of lectures, so I already had a firm grasp on the material before it was presented to the class.

Greatest day of college was the day I stopped giving a crap about grades. Remember you're there to learn not get good grades. It opens everything up, you don't worry about taking difficult classes that will challenge you or overloading on credits. Took classes in every engineering field, economics, business, history, whatever I "wanted" to learn. Seriously it was the greatest realization I had up to that point in my life, never even opened a report card during my senior year or grad school. If you have a solid foundation to build off of learning new things becomes really easy later in life.

Still don't flunk, a B is fine, usually you can get 80% of the results with 20% the effort. Focus on what's valuable to you and forget about the rest.

My current GPA is 3.95 (Purdue CS - not sure if it is top-ranked or not) and I try hard to maintain it. I focus a lot on grades because back in high-school, an accident in grade 10 destroyed my grades and closed a lot of education opportunities (I was restricted to the bed, couldn't go to participate in contests, exams, classmates attended top quality after-school sessions for math and science and I could do none of that - I had very shitty internet - a session would never last long enough to download Vim let alone Linux) When it was time to apply for college, my high school GPA was enough to deny me entry into schools I had dreamed of attending. That humiliation has stuck with me forever. This is one thing in my control, I try my best not to screw things up.

Top hacks: 1) Buy books, learn material before class starts. Then review each section before each class, with notes and questions. You know you are doing it right when everything is boringly obvious by the time you officially get to it. 2) Practice doing problems as fast as possible. During exams, do all problems quickly, keep doing passes through all the questions to fix mistakes until time is up. 3) Explain what you learn to others. This is where you actually start understanding.

According to me, both things have importance weather it is class discussion or books/notes material. There are some extra things that happens other that notes in the class. So keep attending the class teach us a lots of things.

You sacrifice a social life.

I've just read through the replies here and I thought that maybe I'd throw in my two cents. First off, I do not have a 95% average. In fact, I failed 3 out of 5 courses last semester. I had piled Calculus I, Linear Algebra I, and Microeconomics into the same semester and apparently I wasn't ready to take all of those at one time.

Realizing that my GPA was so bad (1.63 as of now) got me pretty depressed. I started Googling how I could fix my GPA and how I could become a better student. I came across a site called StudyHacks (http://calnewport.com/blog/) that had a lot of great articles that were enjoyable to read. I'm going to go to the library in the next week or so and get Cal's book "How to Become a Straight-A Student" (I'd do it now, but I'm reading The Pragmatic Programmer) and I hope that the book will make things more clear.

In the coming year there are a few changes I want to make. The biggest once, contrary to what others on here have said, is that I want to become organized. I've always been the type of person to enjoy what I'll call "organized chaos". There is a place for everything, and that place is wherever it happens to be. That has to change.

The next thing I want to change is that I'm actually going to work on my problem sets. It's been mentioned that problem sets are usually only worth 10 or 15 percent of your final mark. What I find is that while they aren't worth much, not doing your problem sets will affect your test grades in a negative way. Not only are problem sets a grade, they are the best practice that you can get.

The last thing that I want to do is to get involved around my university. We have a CS society that, I'm sad to say, doesn't do much more than drink (not that drinking is a bad thing). I want to get involved with the society, generate new members, and help get the society more active. I have a few ideas that I'm going to bring up with some of the society "executives" that I hope they will like as much as I do.

Obviously I don't have a 95% average, so take everything I say with a grain of salt. I hope it will work for me though. And I think that is the biggest thing there is to consider. Just because something worked for someone else, doesn't mean that it will work for you. Try out different things and see what you like.

At the end of the day, if you have a strong understanding of fundamentals (basic calculus, number theory, C), the rest is just creative applications (eg algorithms, where the motivations for most of the introductory algorithms are easily deduced)

And if you organize your knowledge as such, you can power through 10 CS classes in a semester on top of 4 other required classes

Its seem the comments here are all along the lines of pay attention, do assignments, take notes etc. But how do you keep up with the intensity of doing all this? Is it like weight lifting where at first it feels really uncomfortable, but once you get use to it, it's easy? Also, how do you avoid being bogged down by hard CS assignments (40 hours)? What would a 95% person do in this situation? For example, my cs friend who got 96 told me that he just doesn't sleep and he gets help when he needs it and also he tried to leverage off power of programming language or reusable code. Are there any other hacks?

This is generally applicable advice, but you should realize that time management is about 99% of the problem for most people. In most cases the problem is not that there is too much to do, but rather there is too much to do if you take too long to start doing it. Begin assignments the days they are assigned, for example. This is very hard to do, of course, but successfully managing your own time is the key to academic success.

With rare exception going to class is a no-brainer. Treat school like a full-time job. 100% attendance is an almost necessary (but by no means sufficient) prerequisite for doing well.

I went to college, but was able to get 89% average with about 20 hours a week of homework/studying etc. The girl who beat me, as far as average goes got 99% but spent 60 hours a week on homework/studying.

I was able to tutor 10 students and build two serious web apps in that extra 40 hours a week, who do you think came out on top?
