Dear student. jECA syllabus are completely same the BCA 1to4 sem math syllabus. And total BCA 1to6 sem are computer based questions in jeca. All the best. Preparation tips for the MCA exam:
The number of available vacant seats for the MCA program will be limited in colleges. Due to this reason, the competition will be high at times. For different institutions, accordingly, the syllabus of the examination will be different, so you should keep in mind to not follow a similar pattern. You will need to expand your field of study, mainly in Mathematics and Statistics. You can attend coaching classes or study on your own. You can also get some guide books in order to improve your knowledge. You need to have a good practical knowledge in computer too.
