Some tips for CCEE
Java / DBT / WPT -
•These modules are scoring modules & takes only
30 min to solve the paper.
•If you are good in concepts can easily score 30+
marks.
•Java
topics/concepts to prepare –
o OOPS concepts – 4 pillars, class & objects,
constructors, static, non-static, final, access specifiers, interface etc.,
o Collections – why we use, when we use, what are
the different types & how they differ from each other, thread safe or not,
insertion order maintain or not, null value accepts or not, repeated value
stores or not, only value or key-value pair, sizes & how much increase etc.
o Multi-Threading – code snippets on start, wait,
notify & concepts also.
o Packages – class belongs to which package? Like
StringBuilder, StringBuffer, Thread etc.
o String – code snippets
o JVM, JDK, JRE
o Stack & heap memory – reference stored in
stack & object stores in heap
o Garbage collector
o Exception handling – code snippets & concepts
•DBT
topics/concepts to prepare –
o DBMS intro, RDBMS
o DDL, DCL, DML, DTL commands, difference between
drop, delete and truncate etc.
o Normalization forms 1, 2, 3, BCNF, 4, 5 – concepts
like what is required to have for normalization form.
o All keys, aggregate functions, WHERE, LIKE,
DISTINCT, UNION, NULL
o Stored procedure - concepts
o Cursors - concepts
o Triggers – concepts
o Error Handling and Exceptions – concepts
o NoSQL, why? & examples of NoSQL
o MongoDB – concepts & commands
•
WPT topics/concepts to prepare –
o HTML all tags, some concepts like how to import
css,js file.
o CSS – apply color, border etc.
o Javascript – code snippets on promises &
one-line questions like how to define array in Js.
o nodeJs – concepts & code snippets on its
modules
o express – code snippet on routing
o ReactJs – concepts like props, components, hooks
etc and code snippet
OS
/ DSA
• These modules test takes whole 60 min to solve
because of problems/numerical.
• Problems looks difficult but easy to solve because
they are only for 1 mark.
•
OS topics/concepts to prepare –
o COP – variables, operators, loops, control
statements, functions & oops
o Linux commands
o Process scheduling algorithms numerical– FCFS,
Shortest Job First, Priority, RR
o fork()
o Parent, child, zombie, orphan process
o Signals
o Memory management - First Fit, Best Fit, worst
Fit, paging & segmentation.
o Deadlock – how it occur, mutex, semaphore,
Deadlock prevention and avoidance
o Page replacement algorithms
o IPC – concepts
•
DSA topics/concepts to prepare –
o Time complexities – searching & sorting.
o Basic Data Structures – Array, stack, queues
o Linked lists – singly, doubly, circular, insertion
deletion - codes and time complexities
o Trees – problems - traversal and concepts – AVL,
ACBT
o Graph – problems - traversal, prim’s, Kruskal,
Adjacency Matrix & list
o Hash functions and hash tables – problem- linear
or quadratic probing
o Sorting – which one is better in which condition?
ASDM
o If you have read and understood all concepts of
SDM then can score good marks
o Git & GitHub commands – 5-6 questions
o Docker/Docker swarm/Kubernetes/Jenkins/Jira– why
we use, there applications, concepts and basic commands.
o SDM concepts – agile, scrum, v-model, SDLC etc….
o Virtualization, cloud, aws, EC2, S3
o Microservices and DevOps
o Testing – black, white & Gray
o Selenium

•Advanced
java topics/concepts to prepare –
o Servlet
o Session Management
o Design Pattern: MVC Pattern
o Life cycle of a JSP page
o JDBC
