Complete guide to CDAC CCAT

Will be regularly updated, keep an eye

Believe in yourself, trust the path you have taken and you will find success.

“You have power over your mind — not outside events. Realize this, and you will find strength.”

What is CDAC ? → You can read about it on their official website.

Why CDAC PG Diploma ? → Its a software development boot camp, it has the power to change your future. It can help you enter Software Industry, no matter from which stream you belong to. CDAC pass outs are respected a lot in industry.

FAQs

You will get a job if you fall under below category AND is willing to put hard work, ready to love and learn technologies.

1. I am from mechanical, civil etc. (non CS IT branch), will I get job after CDAC? → Of course you will get job, more than 50% crowd in CDAC are from non CS-IT background.
2. I am from non CS IT but have less than 60% in graduation or in 10th, 12th ? → Mostly, you will not face any problem. Some companies ( 5 to 10%) may not shortlist you but you will get 35 chances.
3. I am from non Engineering background (MSc Physics, Math, Stats), will I get job? → Yes, you will get the job. You will get less chances than engineering students but you will surely get at least 30 + 5 = 35 Interview chances.

If this person can get a job then so can you. Always believe in yourself — > Non Engineering + below 60% in graduation + more than 7 years of gap + did DAC in 2020 → got above 60% in CDAC exam and got job with 6LPA as full stack java developer.

“I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinion of himself than on the opinion of others.”

Which Institutes are best ?

1. ACTS/Sunbeam Pune: Both are at the top. Recently Sunbeam cut-off is higher, its more in demand. One can choose either and you’ll not go wrong.
2. IACSD/ Karad: Second most fav. Placements of IACSD is at par with Sunbeam and Acts.
3. KP/Vita: Have a very good placement record. Good for people from these cities.

CCAT Exam overview

Please check the website for latest updates

The exam is divided into 3 Sections

1. Section A → General Aptitude. Sample Paper
2. Section B → Computer and programming Concepts. Sample Paper
3. Section C → Computer Architecture (Required for DESD course. For this watch GATE Smasher on YouTube). Sample Paper

This article will focus on Section A + B. (for DAC DBDA DMC DAI etc.)

TOTAL Questions = 100.

Always follow the syllabus, and the good result will follow.

Cut-offs:

1. Sunbeam / Acts : Around 600–700.
2. Sunbeam Karad: 800–1000
3. IACSD: 1000–1200
4. KP: 1600–1800

Education Loan:

Loan can be taken under PMKVY. Talk to bank manager directly.

The loan process will start after 2nd round of counselling when you get allotment letter, you get around 10–14 days to make payment. Reach nearby bank, talk to manager, provide your allotment letter. Generally, most managers will have no idea about CDAC, you have to explain it to them. Its not an easy process but people do get it. If you know someone then it becomes really easy.

Section A (50 Questions)

Section A is general aptitude, containing 3 areas mainly English, Quant and Reasoning.

Understand each section from wherever you feel like, there are plenty of good sources available. It just requires dedication and discipline.

For shortcuts also there are many websites, YouTube. Mrunal is one of them.

For understanding c++ watch the vide. Book is for understanding OOPs, read it only if you have time. BUT if you have time then do read it, its one of the best books on this subject.

If you want to dive deep in c++ → https://www.amazon.in/Effective-Object-Oriented-Construction-Industrial-Strategies/dp/0130867691

This is the book, its expensive but keep an eye on it, if you are lucky you can get it around 1000 second hand on Amazon.

go topic wise, and understand all the topics definition from this website https://en.cppreference.com.

Questions asked are very basic → Constructor, creating object and calling method, access modifier public private etc. friend function. OOPs concepts like inheritance, abstractions, polymorphism etc.
