Office hours:

Here is a calendar of all the office hours that the course staff offer. If you would like to speak to an instructor and you cannot make it to their office hours, send an email to set up a meeting. If you have a general question and cannot make it to anyone’s office hours, post to Piazza (see below).

For the most part, staff members will have the same office hours every week. Before going to someone’s hours, check where they will be on the calendar below. Should there be a change to someone’s hours, there will be a post on Piazza and the calendar will be updated.

While some office hours will be in person, we will use the Khoury Office Hours tool for other office hours. Take these steps to join office hours:
  • Log in with your Khoury account credentials.

  • Go to CS 2510 on the top left.

  • Add your name to the queue. Enter the question you wish to ask. Be as detailed as possible.

  • Log in to Microsoft Teams using your Northeastern credentials. When it is your turn, we will get in touch with you via Teams.

For rooms of in-person office hours, check the Google calendar for location.

Your TAs help run the labs, help grade the exams, and hold office hours. In general, they are apprentice teachers and are here to learn how to run a course. At the same time, though, they are your peers who have taken the course, and can see your problems from your perspective.


If you need help, you may talk to any of the instructors, the TAs or tutors during their office hours.

Use Northeastern email (@northeastern.edu) to reach any of the course staff; usernames are given above.

Piazza is an on-line forum for class discussions. Anybody can post a question and anybody else can reply. (Please do not post grading questions to Piazza. It’s best to email the grader instead for those kinds of questions.)

Before posting, check whether or not your question has already been asked. If it already has been asked and has not yet been answered, provided the question is not more than a day old, it likely will be answered soon. Do not double post.

Posting any parts of a solution to any parts of a homework assignment is considered cheating. You don’t want to do this. Limit your answers to other students to providing clarity when needed and hints when appropriate. This is good practice should you ever want to be a tutor :)

Note: anonymity on Piazza is implemented to make you anonymous to students (if you prefer) but not to staff members.

General Policies


Sec 1: MTWR at 11:40am–1:20pm
        Churchill 103        Razzaq

Lectures policy:

You are required to read the lecture material for the given lecture before coming to class. During the lectures we will discuss the material covered in the required reading, answer questions, provide additional examples and applications. You will be required to participate in and submit class work occassionally.

It is OK if you do not understand everything when you first read it, but reading about the new concept ahead of the time will give you a chance to anticipate the questions you may have and allow you to follow better the details of explanation during the lectures.


All labs meet twice a week on Tuesdays and Thursdays.
  • Section 1 (CRN: 40094): 1:30pm-3:10pm in Richards 300
         TAs: Logan, Manasa, Gavin, Blair, Nolan, Narayan

  • Section 2 (CRN: 40210): 3:20pm-5:00pm in Hurtig 129 Richards 300
         TAs: Jan, Nicholas, Maya, Khanh, Shaan, Ari, Emily

Labs policy

The goal of the labs is to see in practice problems that illustrate the concepts covered in the lectures, and to prepare you for the next programming assignment. Attendance is required.

There is a lot of technical detail related to running Java programs that will be covered in the early labs. Later labs will focus more on design questions and on good Java programming practice.

Lab work

Lab attendance is required. There will be a lab quiz or some lab work to be submitted which will be graded. You are responsible for making sure your submissions go through and that the correct file(s) are submitted. No makeups for lab work are allowed, but we will drop your two lowest lab quiz/work grades. The goal of lab work is to see that you are familiar with the most basic concepts covered during the recent lectures, labs, and assignments.

If you have trouble completing lab work, it would be a good idea to meet with the instructor within the next week, to identify the problems you may have and to help you get back on track.

Computing Environment

You will complete your assignments (other than the first one) using the Eclipse IDE. Though, if you feel more comfortable, you may choose to use another IDE (e.g. NetBeans) or work directly from the command line, but you and your partner must both be comfortable with the chosen programming environment, and the staff may not be able to assist you with issues encountered in other environments.

You will use the handin server to submit your homework. You may submit as many times as you wish, though submitting too frequently may be detected and rate-limited, to ensure fairness for other students. Be aware that close to the deadline when everyone submits all at once, the server will become slower. Don’t wait until the last minute to submit!


There will be one or two problem sets each week. The problem sets often include finger exercises and practice problems, that you are strongly encouraged to look at and confirm that you can solve (but are not required). You are welcome to bring solutions to these problems to the course staff during the semester for informal feedback on how you’re doing.

The graded problems are to be solved collaboratively with your partner when you are assigned one in the second half of the term. The problems will consist of structured programming assignments that may be based on the work done in previous weeks, and may also include more creative projects where you can practice your design skills.

Assignments may not be resubmitted after their deadlines (and late days) have passed.

Due Dates: Mondays and Thursdays at 9:00pm, unless otherwise specified. See the late policy above.

Note: You will submit each problem separately on the handin server. This is for your benefit: the server will attempt to compile and run your program against automated test cases. Having separate submissions for each problem means that a syntax error in one problem won’t immediately prevent your other problems from compiling also. Be careful to submit the correct answers to the correct problems. You are responsible for making sure your submissions go through and that the correct file(s) are submitted.

Your last submission will be graded. It is your job to make sure that the last submission is the one you want us to grade.

Pair Programming

Although the homework problems can be solved individually, you must work on some of the problem sets in pairs in the second half of the term. You will get a partner from your lab section and you will work on labs together as well (although lab submissions are usually individual).

Important Pair programming means that you and your partner work on the problem sets jointly. You read them together and you work on the solutions together. One of the lab’s purposes is to teach you how to work in pairs effectively; indeed, pairs are provably more effective than individuals in programming. The rough idea is this: One of you plays pilot, the other co-pilot. The pilot works on the keyboard and explains aloud what is going on; it is the co-pilot’s responsibility to question everything. After a problem is solved to the satisfaction of both, you must switch roles.

Every partner must be able to solve every homework problem in the end. It is an academic integrity violation to submit work under your name that you have not worked on. Doing so may result in earning a 0 on the work and a report to OSCCR. You may also lose the privelege of working with a partner. Therefore both partners must make the effort to meet regularly and work together on every part of the assignments/labs.

If you are having difficulties working with your partner, please inform your lab TA or your instructor quickly: we cannot help if we don’t know there’s a problem. We will check in periodically to assess how the partnerships are going.

Academic Integrity

Any and all submitted work must be your own. If an assignment/lab is to be completed individually, only you and the course staff are allowed to look at your code. If an assignment/lab is to be completed with a partner, only you, your partner and the course staff are allowed to look at your code (see above as well about working with a partner). Use of material from previous classes, solution manuals, material from the Internet or other sources (such as AI assisted tools like ChatGPT or sources such as parents, friends, siblings etc.) that directly bears on the answers is strictly prohibited.

You are allowed to discuss the problem sets with others, so long as you acknowledge (in comments, in your submitted files) whoever you discussed the problem with. Discussing the "what to solve" is OK, discussing "how to solve" is a slippery slope. Once you start discussing possible solutions, you may not realize when you have crossed the line. Ultimately we will judge you by the work you submit. If you think you are smart enough to use somebody’s code and hide it well enough to deceive us, please channel that intelligence towards completing the assignment yourself! Doing the assignments yourself is essential for doing well on the exams which tend to be higher stakes than homework.

NOTE: Be aware that while submitting someone else’s code is clearly a violation, so is sharing your code with others, even if you truly just mean to help. You will be doing your friend or peer a disservice by helping them this way. Please direct them to the course staff instead.

Outside an academic environment, sharing code with unauthorized parties can be a criminal offense and have severe and unanticipated consequences.

Submitting code that is not your own or sharing your code to unfairly help another student will be considered a violation of the University’s Academic Integrity Policy (page 38 of the 2022-2023 Undergraduate Student Handbook). Violations of academic integrity will be reported to OSCCR, and will have strong consequences on your grade, from an automatic zero on the assignment to failing the course.

If you are ever unsure of whether sharing is unacceptable or not, or you are struggling in the course, please contact one of the course staff. We are here to help.


You may bring one sheet of notes to exams (may be typed or hand-written, one-sided or double-sided).


Your final grade is composed of:
  • 37% homework. Most homeworks will be equally weighted, but larger projects that will take more time will be weighted more heavily.

  • 55% exams, with exact proportions to be determined.

  • 5% lab work

  • 3% class work

The same grade will be assigned for CS2510 and CS2511. You can use the handin server to see the current weights of each assignment, and your approximate grade in the course so far. The exact weights of assignments, quizzes and exams may change during the semester, depending on exactly how many of each we have. We will try to keep weight changes as infrequent as possible.

The grades will be computed on an absolute basis: there will be no overall curving. The instructor may choose to curve an individual homework or exam, but please do not bank on such a chance.

The mapping of raw point totals to letter grades is given below. Please note that these grade boundaries may move slightly at the discretion of the instructor, but the grade boundary for A is unlikely to change. Grades are not rounded: for instance, earning a 92.5% does not imply we will round up to a 93% and hence to an A.

Range:          93%   90%   86%   83%   80%   76%   73%   70%   66%   63%   60%   0%
Letter grade:   A     A-    B+    B     B-    C+    C     C-    D+    D     D-    F
