No, you cannot become a lawyer without a Law degree. You mandatorily need to obtain degrees such as BA/BCom/BSc/BBA LLB or LLB in order to be a lawyer in India. To become a lawyer, one must first complete three-year or five-year LLB from a recognised university and possess degree certificate. Then, they must enrol themselves in local Bar Council of the concerned state and enrolled as an advocate. Within two years of the enrolment, they must appear and clear AIBE in order to be eligible to practise anywhere in India. 

Both the AP LAWCET and CLAT entrance exam are conducted for admission to the Law schools in India, however, the syllabus for these exams are different on many parameters and candidates should strategise differently for both the exams. AP LAWCET exam has sections including Current Affairs, Legal Aptitude, Contract Law, Constitution, etc. and the CLAT entrance exam sections include English Language, Legal Aptitude, Mathematics, etc. AP LAWCET does not have mathematics subjects, AP LAWCET exam focus more on regional knowledge. CLAT generally covers the deeper aspects of the particular subject. 

No, After completing LLB you become a lawyer, however, you are still not an advocate and hence cannot practice law. To become an advocate and to practice law as a profession, you mandatorily need to clear the All India Bar Examination (AIBE). After qualifying AIBE, one can practice law as a full fledged profession.
