A limited number of students are allowed to change from the branch allotted to them at the time of admission. Such changes are made on the basis of the Cumulative Performance Index (CPI) of the student at the end of the first two semesters. The rules governing branch changes are somewhat complicated and for exact conditions, students may contact academic office. The following is a rough guideline. Branch change is strictly on merit across the class. What this implies is that if a student is not allowed to change branch to a discipline of his choice, for restrictions imposed by other rules governing such change, no other student having a lower CPI than such a denied student will be permitted to change to this particular discipline.
There are some restrictions of transfers from or to a branch. Consequent to branch changes, the strength ofa should not fall below 85% of its strength on rolls before effecting such changes. Similarly, the strength of a branch cannot exceed the sanctioned strength for that branch. The implication of these rules is that it is more difficult to get a branch change from branches having a small sanctioned strength. Further, because of such restriction, a student who desires a branch change from such a class may get denied a change of branch and block students across other disciplines to change branches because of the merit criterion. Request for branch changes from students belonging to reserved category are considered separately on merit of each case.

B.Tech./Integrated M.Sc./Dual Degree
All students admitted to any of the above programmes undergo a common academic programme for the First semester (LINK). The second semester consists of mostly common courses, except that a student must take one Departmental Introductory course (DIC) and another Departmental Optional Course (DOC). A limited number of students are allowed to change their branches based on
their performance at the end of first year. Every course taken by a student (other than requirements like NCC/NSO or Practical Training) have a credit associated with it. Generally, one hour of theory course (lecture or tutorial) carries two credits while an hour in a laboratory course carries one credit. A course structure 2-1-0-6 implies that it has 2 lecture hours, one tutorial hour and nil (0) practical hours associated with it. The total credit for such a course is 2x2+1x2+0x1 = 6 credits. Similarly, a 0-1-3-5 structure implies one tutorial hour and three practical hours with a total of 5 credits. The credit structure for the courses may be seen from the concerned department's page.
The Institute follows a continuous evaluation system with considerable freedom being given to the course Instructor in deciding the pattern
of evaluation. However, a typical theory course will have a mid-semester examination carrying 30 marks, one or two quizes or mini tests carrying 20 marks and an end of semester examination carrying 50 marks. The total marks thus received is converted to a letter grade, based on the relative (and some times the absolute) performance of the student. The grades are on a scale of 10 with the grade AA being the best and FF and FR being fail grades. Each letter grade has a grade point associated with it, as follows :
| Grades | AA | AB | BB | BC | CC | CD | DD | FF | FR |
| Points | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 0 Fail Grade, eligible for a re-examination. | 0 Fail Grade, must repeat the course. |
Other grades like P (Passed), NP (Not Passed), Au (Audit Course) do not have any grade points associated with them. The performance of a student in a particular semester is measured by Semester Performance Index (SPI), which is a weghted average of the grades secured in all the courses taken in a semester and scaled to a maximum 10.For instance, suppose a student is registered for one 8 credit course, four 6 credit courses, one 5 credit course and one 3 credit course during a semester, i.e. a total of 40 credits. If he secures AB, BB, BC, CC, AB, AA, CD grades respecively in these courses, his SPI will be calculated as follows :
SPI = (9x8 + 8x6 + 7x6 + 6x6 + 9x6 + 10x5 + 5x3)/40= 317/40 = 7.92
SPI is calculated upto two decimal places.
In a very similar manner a Cumulative Performance Index (CPI) of a student is calculated, taking into account the performance in all courses taken by a student upto the semester for which the result is last available.
M.Sc. (Post B.Sc. programmes)
The post B.Sc. masters' programmes follow a credit structure and evaluation pattern similar to what is stated for B.Tech.
B.Tech. Project (BTP)/M.Sc. Project :
In addition to prescribed course work every student in B.Tech.or M.Sc. has to do a one year dissertation under guidance of
a supervisor approved by the Department. (In case of M.Sc.,the project is often referred to as "home paper"). The project
is evaluated in two stages, once by an internal board of examiners at the end of the pre-final semester and finally at the end of
final semester, when an examiner external to IITB is also present. Typically, the project carries 20 credits.
Practical Training :
Every B.Tech. student is required to undergo a practical training (PT) in a factory, laboratory, work-site or organisation as may be
approved by the Department. The training may be taken either continuously after the sixth semester or in two separate spells of four weeks each after the fourth and the sixth semesters. After the training, a student is required to submit a written report to the Department for evaluation and approval. A Pass (P) or a No Pass (NP) grade without credit is attached to this essential requirement of the B.Tech. degree.
