Different universities and colleges have different requirements for BCA (Bachelor of Computer Applications) entrance exams. IP University, Christ University and Symbiosis have an institutional entrance, meaning that students will have to take an exam specific for them. Other colleges provide admissions based on merit and weigh the marks from the 12th grade. Usually, competitive universities use entrance examinations to test a student's skills in areas such as mathematics, logical reasoning, and general knowledge.
On the contrary, many private and state universities simply offer admission to students who pass their cut-off marks or fall under the management quota. If you are eyeing a good college, then you should go through their website for detailed admission information. Generally, students should have completed 12th grade with mathematics or computer science. Students, if required, should pay attention to quantitative aptitude, reasoning, and basic programming for entrance exams. Studying different universities and their entrance requirements will make the whole process smooth.
